Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131894, here are decompositions:

  • 3 + 131891 = 131894
  • 97 + 131797 = 131894
  • 151 + 131743 = 131894
  • 163 + 131731 = 131894
  • 181 + 131713 = 131894
  • 193 + 131701 = 131894
  • 223 + 131671 = 131894
  • 277 + 131617 = 131894

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 131,894 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 131894 first appears in π at position 598,805 of the decimal expansion (the 598,805ordinal-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.
