Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136566, here are decompositions:

  • 7 + 136559 = 136566
  • 19 + 136547 = 136566
  • 29 + 136537 = 136566
  • 43 + 136523 = 136566
  • 47 + 136519 = 136566
  • 83 + 136483 = 136566
  • 103 + 136463 = 136566
  • 113 + 136453 = 136566

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 136,566 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 136566 first appears in π at position 722,082 of the decimal expansion (the 722,082ordinal-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.
