Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490356, here are decompositions:

  • 17 + 490339 = 490356
  • 43 + 490313 = 490356
  • 47 + 490309 = 490356
  • 73 + 490283 = 490356
  • 79 + 490277 = 490356
  • 89 + 490267 = 490356
  • 107 + 490249 = 490356
  • 109 + 490247 = 490356

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 490,356 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 490356 first appears in π at position 679,042 of the decimal expansion (the 679,042ordinal-suffix:nd 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.
