Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131954, here are decompositions:

  • 7 + 131947 = 131954
  • 13 + 131941 = 131954
  • 61 + 131893 = 131954
  • 157 + 131797 = 131954
  • 211 + 131743 = 131954
  • 223 + 131731 = 131954
  • 241 + 131713 = 131954
  • 283 + 131671 = 131954

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 131,954 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 131954 first appears in π at position 627,686 of the decimal expansion (the 627,686ordinal-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.
