Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489784, here are decompositions:

  • 23 + 489761 = 489784
  • 41 + 489743 = 489784
  • 107 + 489677 = 489784
  • 131 + 489653 = 489784
  • 227 + 489557 = 489784
  • 233 + 489551 = 489784
  • 353 + 489431 = 489784
  • 521 + 489263 = 489784

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 489,784 and was likely granted around 1892.

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