Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999290, here are decompositions:

  • 3 + 999287 = 999290
  • 73 + 999217 = 999290
  • 109 + 999181 = 999290
  • 157 + 999133 = 999290
  • 199 + 999091 = 999290
  • 223 + 999067 = 999290
  • 241 + 999049 = 999290
  • 283 + 999007 = 999290

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 999,290 and was likely granted around 1911.

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