Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490494, here are decompositions:

  • 13 + 490481 = 490494
  • 31 + 490463 = 490494
  • 41 + 490453 = 490494
  • 73 + 490421 = 490494
  • 101 + 490393 = 490494
  • 127 + 490367 = 490494
  • 181 + 490313 = 490494
  • 211 + 490283 = 490494

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 490,494 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 490494 first appears in π at position 559,934 of the decimal expansion (the 559,934ordinal-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.
