Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488840, here are decompositions:

  • 7 + 488833 = 488840
  • 13 + 488827 = 488840
  • 19 + 488821 = 488840
  • 43 + 488797 = 488840
  • 61 + 488779 = 488840
  • 97 + 488743 = 488840
  • 139 + 488701 = 488840
  • 151 + 488689 = 488840

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 488,840 and was likely granted around 1892.

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