Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490668, here are decompositions:

  • 5 + 490663 = 490668
  • 7 + 490661 = 490668
  • 37 + 490631 = 490668
  • 41 + 490627 = 490668
  • 89 + 490579 = 490668
  • 97 + 490571 = 490668
  • 109 + 490559 = 490668
  • 127 + 490541 = 490668

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 490,668 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 490668 first appears in π at position 547,601 of the decimal expansion (the 547,601ordinal-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.
