Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009420, here are decompositions:

  • 3 + 1009417 = 1009420
  • 47 + 1009373 = 1009420
  • 59 + 1009361 = 1009420
  • 101 + 1009319 = 1009420
  • 131 + 1009289 = 1009420
  • 173 + 1009247 = 1009420
  • 227 + 1009193 = 1009420
  • 257 + 1009163 = 1009420

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 1,009,420 and was likely granted around 1911.

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