Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131946, here are decompositions:

  • 5 + 131941 = 131946
  • 7 + 131939 = 131946
  • 13 + 131933 = 131946
  • 19 + 131927 = 131946
  • 37 + 131909 = 131946
  • 47 + 131899 = 131946
  • 53 + 131893 = 131946
  • 97 + 131849 = 131946

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 131,946 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 131946 first appears in π at position 592,901 of the decimal expansion (the 592,901ordinal-suffix:st 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.
