Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131454, here are decompositions:

  • 5 + 131449 = 131454
  • 7 + 131447 = 131454
  • 13 + 131441 = 131454
  • 17 + 131437 = 131454
  • 23 + 131431 = 131454
  • 41 + 131413 = 131454
  • 73 + 131381 = 131454
  • 83 + 131371 = 131454

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 131,454 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 131454 first appears in π at position 529,292 of the decimal expansion (the 529,292ordinal-suffix:nd 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.
