Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109986, here are decompositions:

  • 43 + 109943 = 109986
  • 67 + 109919 = 109986
  • 73 + 109913 = 109986
  • 83 + 109903 = 109986
  • 89 + 109897 = 109986
  • 103 + 109883 = 109986
  • 113 + 109873 = 109986
  • 127 + 109859 = 109986

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 109,986 and was likely granted around 1871.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 109986 first appears in π at position 683,991 of the decimal expansion (the 683,991ordinal-suffix:st 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.
