Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990284, here are decompositions:

  • 3 + 990281 = 990284
  • 7 + 990277 = 990284
  • 73 + 990211 = 990284
  • 103 + 990181 = 990284
  • 241 + 990043 = 990284
  • 271 + 990013 = 990284
  • 283 + 990001 = 990284
  • 307 + 989977 = 990284

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 990,284 and was likely granted around 1911.

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