Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490872, here are decompositions:

  • 13 + 490859 = 490872
  • 23 + 490849 = 490872
  • 43 + 490829 = 490872
  • 89 + 490783 = 490872
  • 101 + 490771 = 490872
  • 103 + 490769 = 490872
  • 131 + 490741 = 490872
  • 139 + 490733 = 490872

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 490,872 and was likely granted around 1892.

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