Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489902, here are decompositions:

  • 31 + 489871 = 489902
  • 79 + 489823 = 489902
  • 103 + 489799 = 489902
  • 109 + 489793 = 489902
  • 211 + 489691 = 489902
  • 223 + 489679 = 489902
  • 229 + 489673 = 489902
  • 271 + 489631 = 489902

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 489,902 and was likely granted around 1892.

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