Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188724, here are decompositions:

  • 5 + 188719 = 188724
  • 13 + 188711 = 188724
  • 17 + 188707 = 188724
  • 23 + 188701 = 188724
  • 31 + 188693 = 188724
  • 37 + 188687 = 188724
  • 43 + 188681 = 188724
  • 47 + 188677 = 188724

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 188,724 and was likely granted around 1875.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 188724 first appears in π at position 68,685 of the decimal expansion (the 68,685ordinal-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.
