Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136512, here are decompositions:

  • 11 + 136501 = 136512
  • 29 + 136483 = 136512
  • 31 + 136481 = 136512
  • 41 + 136471 = 136512
  • 59 + 136453 = 136512
  • 83 + 136429 = 136512
  • 109 + 136403 = 136512
  • 113 + 136399 = 136512

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 136,512 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 136512 first appears in π at position 287,059 of the decimal expansion (the 287,059ordinal-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.
