Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997320, here are decompositions:

  • 11 + 997309 = 997320
  • 13 + 997307 = 997320
  • 41 + 997279 = 997320
  • 47 + 997273 = 997320
  • 53 + 997267 = 997320
  • 61 + 997259 = 997320
  • 73 + 997247 = 997320
  • 101 + 997219 = 997320

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 997,320 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 997320 first appears in π at position 339,924 of the decimal expansion (the 339,924ordinal-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.
