Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123650, here are decompositions:

  • 13 + 123637 = 123650
  • 19 + 123631 = 123650
  • 31 + 123619 = 123650
  • 67 + 123583 = 123650
  • 97 + 123553 = 123650
  • 103 + 123547 = 123650
  • 151 + 123499 = 123650
  • 157 + 123493 = 123650

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 123,650 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 123650 first appears in π at position 115,169 of the decimal expansion (the 115,169ordinal-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.
