Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989904, here are decompositions:

  • 17 + 989887 = 989904
  • 31 + 989873 = 989904
  • 67 + 989837 = 989904
  • 73 + 989831 = 989904
  • 101 + 989803 = 989904
  • 107 + 989797 = 989904
  • 127 + 989777 = 989904
  • 151 + 989753 = 989904

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 989,904 and was likely granted around 1911.

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