Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120866, here are decompositions:

  • 3 + 120863 = 120866
  • 19 + 120847 = 120866
  • 37 + 120829 = 120866
  • 43 + 120823 = 120866
  • 103 + 120763 = 120866
  • 127 + 120739 = 120866
  • 157 + 120709 = 120866
  • 439 + 120427 = 120866

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 120,866 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 120866 first appears in π at position 631,982 of the decimal expansion (the 631,982ordinal-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.
