Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992720, here are decompositions:

  • 13 + 992707 = 992720
  • 19 + 992701 = 992720
  • 31 + 992689 = 992720
  • 61 + 992659 = 992720
  • 97 + 992623 = 992720
  • 181 + 992539 = 992720
  • 199 + 992521 = 992720
  • 271 + 992449 = 992720

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 992,720 and was likely granted around 1911.

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

Position in π

The digit sequence 992720 first appears in π at position 269,520 of the decimal expansion (the 269,520ordinal-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.
