Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123982, here are decompositions:

  • 3 + 123979 = 123982
  • 29 + 123953 = 123982
  • 41 + 123941 = 123982
  • 59 + 123923 = 123982
  • 71 + 123911 = 123982
  • 149 + 123833 = 123982
  • 179 + 123803 = 123982
  • 191 + 123791 = 123982

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 123,982 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 123982 first appears in π at position 50,092 of the decimal expansion (the 50,092ordinal-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.
