Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997420, here are decompositions:

  • 29 + 997391 = 997420
  • 41 + 997379 = 997420
  • 101 + 997319 = 997420
  • 113 + 997307 = 997420
  • 173 + 997247 = 997420
  • 257 + 997163 = 997420
  • 269 + 997151 = 997420
  • 311 + 997109 = 997420

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 997,420 and was likely granted around 1911.

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