Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990446, here are decompositions:

  • 97 + 990349 = 990446
  • 139 + 990307 = 990446
  • 157 + 990289 = 990446
  • 277 + 990169 = 990446
  • 283 + 990163 = 990446
  • 409 + 990037 = 990446
  • 433 + 990013 = 990446
  • 487 + 989959 = 990446

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 990,446 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 990446 first appears in π at position 563,259 of the decimal expansion (the 563,259ordinal-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.
