Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135986, here are decompositions:

  • 7 + 135979 = 135986
  • 73 + 135913 = 135986
  • 127 + 135859 = 135986
  • 157 + 135829 = 135986
  • 199 + 135787 = 135986
  • 229 + 135757 = 135986
  • 337 + 135649 = 135986
  • 349 + 135637 = 135986

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 135,986 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 135986 first appears in π at position 756,222 of the decimal expansion (the 756,222ordinal-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.
