Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490828, here are decompositions:

  • 59 + 490769 = 490828
  • 131 + 490697 = 490828
  • 167 + 490661 = 490828
  • 197 + 490631 = 490828
  • 251 + 490577 = 490828
  • 257 + 490571 = 490828
  • 269 + 490559 = 490828
  • 347 + 490481 = 490828

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 490,828 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 490828 first appears in π at position 686,891 of the decimal expansion (the 686,891ordinal-suffix:st 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.
