Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997528, here are decompositions:

  • 17 + 997511 = 997528
  • 89 + 997439 = 997528
  • 101 + 997427 = 997528
  • 137 + 997391 = 997528
  • 149 + 997379 = 997528
  • 269 + 997259 = 997528
  • 281 + 997247 = 997528
  • 419 + 997109 = 997528

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 997,528 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 997528 first appears in π at position 861,629 of the decimal expansion (the 861,629ordinal-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.
