Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002420, here are decompositions:

  • 17 + 1002403 = 1002420
  • 43 + 1002377 = 1002420
  • 59 + 1002361 = 1002420
  • 61 + 1002359 = 1002420
  • 71 + 1002349 = 1002420
  • 73 + 1002347 = 1002420
  • 79 + 1002341 = 1002420
  • 131 + 1002289 = 1002420

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 1,002,420 and was likely granted around 1911.

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