Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123836, here are decompositions:

  • 3 + 123833 = 123836
  • 7 + 123829 = 123836
  • 19 + 123817 = 123836
  • 79 + 123757 = 123836
  • 103 + 123733 = 123836
  • 109 + 123727 = 123836
  • 199 + 123637 = 123836
  • 283 + 123553 = 123836

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 123,836 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 123836 first appears in π at position 624,826 of the decimal expansion (the 624,826ordinal-suffix:th 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.
