Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131884, here are decompositions:

  • 23 + 131861 = 131884
  • 47 + 131837 = 131884
  • 101 + 131783 = 131884
  • 107 + 131777 = 131884
  • 113 + 131771 = 131884
  • 173 + 131711 = 131884
  • 197 + 131687 = 131884
  • 257 + 131627 = 131884

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 131,884 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 131884 first appears in π at position 161,628 of the decimal expansion (the 161,628ordinal-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.
