Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989916, here are decompositions:

  • 7 + 989909 = 989916
  • 29 + 989887 = 989916
  • 43 + 989873 = 989916
  • 47 + 989869 = 989916
  • 79 + 989837 = 989916
  • 89 + 989827 = 989916
  • 113 + 989803 = 989916
  • 139 + 989777 = 989916

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 989,916 and was likely granted around 1911.

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