Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489688, here are decompositions:

  • 11 + 489677 = 489688
  • 29 + 489659 = 489688
  • 131 + 489557 = 489688
  • 137 + 489551 = 489688
  • 149 + 489539 = 489688
  • 239 + 489449 = 489688
  • 257 + 489431 = 489688
  • 281 + 489407 = 489688

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 489,688 and was likely granted around 1892.

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