Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131076, here are decompositions:

  • 5 + 131071 = 131076
  • 13 + 131063 = 131076
  • 17 + 131059 = 131076
  • 53 + 131023 = 131076
  • 67 + 131009 = 131076
  • 89 + 130987 = 131076
  • 103 + 130973 = 131076
  • 107 + 130969 = 131076

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 131,076 and was likely granted around 1872.

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.

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 131076 first appears in π at position 37,563 of the decimal expansion (the 37,563ordinal-suffix:rd 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.
