Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994640, here are decompositions:

  • 19 + 994621 = 994640
  • 37 + 994603 = 994640
  • 61 + 994579 = 994640
  • 79 + 994561 = 994640
  • 139 + 994501 = 994640
  • 151 + 994489 = 994640
  • 193 + 994447 = 994640
  • 223 + 994417 = 994640

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 994,640 and was likely granted around 1911.

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