Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108986, here are decompositions:

  • 19 + 108967 = 108986
  • 37 + 108949 = 108986
  • 43 + 108943 = 108986
  • 79 + 108907 = 108986
  • 103 + 108883 = 108986
  • 109 + 108877 = 108986
  • 193 + 108793 = 108986
  • 277 + 108709 = 108986

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 108,986 and was likely granted around 1871.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.

000108986
Federal Reserve
United States Government

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.

Position in π

The digit sequence 108986 first appears in π at position 526,738 of the decimal expansion (the 526,738ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
