Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478668, here are decompositions:

  • 17 + 478651 = 478668
  • 31 + 478637 = 478668
  • 37 + 478631 = 478668
  • 41 + 478627 = 478668
  • 79 + 478589 = 478668
  • 89 + 478579 = 478668
  • 97 + 478571 = 478668
  • 137 + 478531 = 478668

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 478,668 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
