Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990002, here are decompositions:

  • 3 + 989999 = 990002
  • 31 + 989971 = 990002
  • 43 + 989959 = 990002
  • 73 + 989929 = 990002
  • 163 + 989839 = 990002
  • 199 + 989803 = 990002
  • 241 + 989761 = 990002
  • 283 + 989719 = 990002

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 990,002 and was likely granted around 1911.

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