Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118920, here are decompositions:

  • 7 + 118913 = 118920
  • 13 + 118907 = 118920
  • 17 + 118903 = 118920
  • 19 + 118901 = 118920
  • 23 + 118897 = 118920
  • 29 + 118891 = 118920
  • 47 + 118873 = 118920
  • 59 + 118861 = 118920

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 118,920 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 118920 first appears in π at position 356,281 of the decimal expansion (the 356,281ordinal-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.
