Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990492, here are decompositions:

  • 5 + 990487 = 990492
  • 23 + 990469 = 990492
  • 29 + 990463 = 990492
  • 103 + 990389 = 990492
  • 109 + 990383 = 990492
  • 131 + 990361 = 990492
  • 163 + 990329 = 990492
  • 179 + 990313 = 990492

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 990,492 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 990492 first appears in π at position 323,075 of the decimal expansion (the 323,075ordinal-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.
