Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998770, here are decompositions:

  • 11 + 998759 = 998770
  • 53 + 998717 = 998770
  • 83 + 998687 = 998770
  • 89 + 998681 = 998770
  • 137 + 998633 = 998770
  • 233 + 998537 = 998770
  • 257 + 998513 = 998770
  • 347 + 998423 = 998770

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 998,770 and was likely granted around 1911.

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