Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990564, here are decompositions:

  • 5 + 990559 = 990564
  • 17 + 990547 = 990564
  • 41 + 990523 = 990564
  • 53 + 990511 = 990564
  • 61 + 990503 = 990564
  • 67 + 990497 = 990564
  • 101 + 990463 = 990564
  • 167 + 990397 = 990564

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 990,564 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 990564 first appears in π at position 609,220 of the decimal expansion (the 609,220ordinal-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.
