Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489420, here are decompositions:

  • 11 + 489409 = 489420
  • 13 + 489407 = 489420
  • 31 + 489389 = 489420
  • 53 + 489367 = 489420
  • 59 + 489361 = 489420
  • 83 + 489337 = 489420
  • 137 + 489283 = 489420
  • 157 + 489263 = 489420

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 489,420 and was likely granted around 1892.

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