Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131764, here are decompositions:

  • 5 + 131759 = 131764
  • 53 + 131711 = 131764
  • 137 + 131627 = 131764
  • 173 + 131591 = 131764
  • 257 + 131507 = 131764
  • 263 + 131501 = 131764
  • 317 + 131447 = 131764
  • 383 + 131381 = 131764

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 131,764 and was likely granted around 1872.

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

Position in π

The digit sequence 131764 first appears in π at position 81,198 of the decimal expansion (the 81,198ordinal-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.
