Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136988, here are decompositions:

  • 37 + 136951 = 136988
  • 109 + 136879 = 136988
  • 127 + 136861 = 136988
  • 139 + 136849 = 136988
  • 211 + 136777 = 136988
  • 277 + 136711 = 136988
  • 331 + 136657 = 136988
  • 337 + 136651 = 136988

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 136,988 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 136988 first appears in π at position 3,466 of the decimal expansion (the 3,466ordinal-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.
