Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490500, here are decompositions:

  • 7 + 490493 = 490500
  • 19 + 490481 = 490500
  • 37 + 490463 = 490500
  • 41 + 490459 = 490500
  • 47 + 490453 = 490500
  • 79 + 490421 = 490500
  • 83 + 490417 = 490500
  • 107 + 490393 = 490500

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 490,500 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 490500 first appears in π at position 519,496 of the decimal expansion (the 519,496ordinal-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.
