Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123724, here are decompositions:

  • 5 + 123719 = 123724
  • 17 + 123707 = 123724
  • 23 + 123701 = 123724
  • 47 + 123677 = 123724
  • 71 + 123653 = 123724
  • 131 + 123593 = 123724
  • 173 + 123551 = 123724
  • 197 + 123527 = 123724

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 123,724 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 123724 first appears in π at position 199,623 of the decimal expansion (the 199,623ordinal-suffix:rd 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.
