Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111908, here are decompositions:

  • 37 + 111871 = 111908
  • 61 + 111847 = 111908
  • 79 + 111829 = 111908
  • 109 + 111799 = 111908
  • 127 + 111781 = 111908
  • 157 + 111751 = 111908
  • 211 + 111697 = 111908
  • 241 + 111667 = 111908

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 111,908 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 111908 first appears in π at position 843,272 of the decimal expansion (the 843,272ordinal-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.
