Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498980, here are decompositions:

  • 3 + 498977 = 498980
  • 7 + 498973 = 498980
  • 19 + 498961 = 498980
  • 43 + 498937 = 498980
  • 73 + 498907 = 498980
  • 193 + 498787 = 498980
  • 199 + 498781 = 498980
  • 241 + 498739 = 498980

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 498,980 and was likely granted around 1893.

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