Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990622, here are decompositions:

  • 23 + 990599 = 990622
  • 29 + 990593 = 990622
  • 233 + 990389 = 990622
  • 239 + 990383 = 990622
  • 251 + 990371 = 990622
  • 263 + 990359 = 990622
  • 293 + 990329 = 990622
  • 383 + 990239 = 990622

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 990,622 and was likely granted around 1911.

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