Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123722, here are decompositions:

  • 3 + 123719 = 123722
  • 61 + 123661 = 123722
  • 103 + 123619 = 123722
  • 139 + 123583 = 123722
  • 223 + 123499 = 123722
  • 229 + 123493 = 123722
  • 283 + 123439 = 123722
  • 349 + 123373 = 123722

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 123,722 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 123722 first appears in π at position 234,780 of the decimal expansion (the 234,780ordinal-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.
