Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490868, here are decompositions:

  • 19 + 490849 = 490868
  • 31 + 490837 = 490868
  • 97 + 490771 = 490868
  • 127 + 490741 = 490868
  • 241 + 490627 = 490868
  • 277 + 490591 = 490868
  • 331 + 490537 = 490868
  • 349 + 490519 = 490868

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 490,868 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 490868 first appears in π at position 379,782 of the decimal expansion (the 379,782ordinal-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.
