Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999522, here are decompositions:

  • 23 + 999499 = 999522
  • 31 + 999491 = 999522
  • 71 + 999451 = 999522
  • 89 + 999433 = 999522
  • 151 + 999371 = 999522
  • 163 + 999359 = 999522
  • 191 + 999331 = 999522
  • 193 + 999329 = 999522

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 999,522 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 999522 first appears in π at position 355,793 of the decimal expansion (the 355,793ordinal-suffix:rd 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.
