Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509420, here are decompositions:

  • 3 + 509417 = 509420
  • 7 + 509413 = 509420
  • 31 + 509389 = 509420
  • 61 + 509359 = 509420
  • 103 + 509317 = 509420
  • 127 + 509293 = 509420
  • 139 + 509281 = 509420
  • 157 + 509263 = 509420

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 509,420 and was likely granted around 1893.

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