Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999726, here are decompositions:

  • 5 + 999721 = 999726
  • 43 + 999683 = 999726
  • 59 + 999667 = 999726
  • 73 + 999653 = 999726
  • 103 + 999623 = 999726
  • 113 + 999613 = 999726
  • 127 + 999599 = 999726
  • 163 + 999563 = 999726

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 999,726 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 999726 first appears in π at position 323,263 of the decimal expansion (the 323,263ordinal-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.
