Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136810, here are decompositions:

  • 41 + 136769 = 136810
  • 59 + 136751 = 136810
  • 71 + 136739 = 136810
  • 83 + 136727 = 136810
  • 101 + 136709 = 136810
  • 251 + 136559 = 136810
  • 263 + 136547 = 136810
  • 269 + 136541 = 136810

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 136,810 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 136810 first appears in π at position 642,543 of the decimal expansion (the 642,543ordinal-suffix:rd 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.
