Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118980, here are decompositions:

  • 7 + 118973 = 118980
  • 13 + 118967 = 118980
  • 53 + 118927 = 118980
  • 67 + 118913 = 118980
  • 73 + 118907 = 118980
  • 79 + 118901 = 118980
  • 83 + 118897 = 118980
  • 89 + 118891 = 118980

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 118,980 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 118980 first appears in π at position 627,792 of the decimal expansion (the 627,792ordinal-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.
