Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136806, here are decompositions:

  • 29 + 136777 = 136806
  • 37 + 136769 = 136806
  • 53 + 136753 = 136806
  • 67 + 136739 = 136806
  • 73 + 136733 = 136806
  • 79 + 136727 = 136806
  • 97 + 136709 = 136806
  • 113 + 136693 = 136806

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 136,806 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 136806 first appears in π at position 709,528 of the decimal expansion (the 709,528ordinal-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.
