Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136880, here are decompositions:

  • 19 + 136861 = 136880
  • 31 + 136849 = 136880
  • 67 + 136813 = 136880
  • 103 + 136777 = 136880
  • 127 + 136753 = 136880
  • 223 + 136657 = 136880
  • 229 + 136651 = 136880
  • 277 + 136603 = 136880

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 136,880 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 136880 first appears in π at position 656,794 of the decimal expansion (the 656,794ordinal-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.
