Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997158, here are decompositions:

  • 5 + 997153 = 997158
  • 7 + 997151 = 997158
  • 11 + 997147 = 997158
  • 17 + 997141 = 997158
  • 37 + 997121 = 997158
  • 47 + 997111 = 997158
  • 59 + 997099 = 997158
  • 61 + 997097 = 997158

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 997,158 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 997158 first appears in π at position 359,384 of the decimal expansion (the 359,384ordinal-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.
