Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135566, here are decompositions:

  • 7 + 135559 = 135566
  • 97 + 135469 = 135566
  • 103 + 135463 = 135566
  • 139 + 135427 = 135566
  • 157 + 135409 = 135566
  • 163 + 135403 = 135566
  • 199 + 135367 = 135566
  • 283 + 135283 = 135566

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 135,566 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 135566 first appears in π at position 336,344 of the decimal expansion (the 336,344ordinal-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.
