Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108920, here are decompositions:

  • 3 + 108917 = 108920
  • 13 + 108907 = 108920
  • 37 + 108883 = 108920
  • 43 + 108877 = 108920
  • 127 + 108793 = 108920
  • 151 + 108769 = 108920
  • 181 + 108739 = 108920
  • 193 + 108727 = 108920

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 108,920 and was likely granted around 1871.

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

Position in π

The digit sequence 108920 first appears in π at position 277,379 of the decimal expansion (the 277,379ordinal-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.
