Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490764, here are decompositions:

  • 23 + 490741 = 490764
  • 31 + 490733 = 490764
  • 67 + 490697 = 490764
  • 101 + 490663 = 490764
  • 103 + 490661 = 490764
  • 137 + 490627 = 490764
  • 173 + 490591 = 490764
  • 191 + 490573 = 490764

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 490,764 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 490764 first appears in π at position 955,758 of the decimal expansion (the 955,758ordinal-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.
