Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991962, here are decompositions:

  • 5 + 991957 = 991962
  • 11 + 991951 = 991962
  • 19 + 991943 = 991962
  • 31 + 991931 = 991962
  • 53 + 991909 = 991962
  • 61 + 991901 = 991962
  • 73 + 991889 = 991962
  • 79 + 991883 = 991962

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 991,962 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 991962 first appears in π at position 793,423 of the decimal expansion (the 793,423ordinal-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.
