Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490636, here are decompositions:

  • 5 + 490631 = 490636
  • 17 + 490619 = 490636
  • 59 + 490577 = 490636
  • 137 + 490499 = 490636
  • 173 + 490463 = 490636
  • 269 + 490367 = 490636
  • 353 + 490283 = 490636
  • 359 + 490277 = 490636

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 490,636 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 490636 first appears in π at position 132,514 of the decimal expansion (the 132,514ordinal-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.
