Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997230, here are decompositions:

  • 11 + 997219 = 997230
  • 23 + 997207 = 997230
  • 29 + 997201 = 997230
  • 67 + 997163 = 997230
  • 79 + 997151 = 997230
  • 83 + 997147 = 997230
  • 89 + 997141 = 997230
  • 107 + 997123 = 997230

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 997,230 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 997230 first appears in π at position 482,274 of the decimal expansion (the 482,274ordinal-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.
