Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131696, here are decompositions:

  • 79 + 131617 = 131696
  • 199 + 131497 = 131696
  • 283 + 131413 = 131696
  • 379 + 131317 = 131696
  • 547 + 131149 = 131696
  • 673 + 131023 = 131696
  • 709 + 130987 = 131696
  • 727 + 130969 = 131696

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 131,696 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 131696 first appears in π at position 80,867 of the decimal expansion (the 80,867ordinal-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.
