Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990272, here are decompositions:

  • 13 + 990259 = 990272
  • 61 + 990211 = 990272
  • 103 + 990169 = 990272
  • 109 + 990163 = 990272
  • 229 + 990043 = 990272
  • 271 + 990001 = 990272
  • 313 + 989959 = 990272
  • 433 + 989839 = 990272

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 990,272 and was likely granted around 1911.

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