Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720102, here are decompositions:

  • 31 + 8720071 = 8720102
  • 103 + 8719999 = 8720102
  • 151 + 8719951 = 8720102
  • 163 + 8719939 = 8720102
  • 199 + 8719903 = 8720102
  • 229 + 8719873 = 8720102
  • 271 + 8719831 = 8720102
  • 283 + 8719819 = 8720102

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 8,720,102 and was likely granted around 2014.

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