Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009728, here are decompositions:

  • 59 + 1009669 = 1009728
  • 79 + 1009649 = 1009728
  • 101 + 1009627 = 1009728
  • 107 + 1009621 = 1009728
  • 127 + 1009601 = 1009728
  • 191 + 1009537 = 1009728
  • 197 + 1009531 = 1009728
  • 227 + 1009501 = 1009728

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 1,009,728 and was likely granted around 1911.

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