Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987670, here are decompositions:

  • 11 + 987659 = 987670
  • 71 + 987599 = 987670
  • 83 + 987587 = 987670
  • 137 + 987533 = 987670
  • 179 + 987491 = 987670
  • 197 + 987473 = 987670
  • 317 + 987353 = 987670
  • 419 + 987251 = 987670

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 987,670 and was likely granted around 1911.

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