Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997120, here are decompositions:

  • 11 + 997109 = 997120
  • 17 + 997103 = 997120
  • 23 + 997097 = 997120
  • 29 + 997091 = 997120
  • 83 + 997037 = 997120
  • 101 + 997019 = 997120
  • 107 + 997013 = 997120
  • 167 + 996953 = 997120

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 997,120 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 997120 first appears in π at position 3,710 of the decimal expansion (the 3,710ordinal-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.
