Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647130, here are decompositions:

  • 3 + 8647127 = 8647130
  • 7 + 8647123 = 8647130
  • 67 + 8647063 = 8647130
  • 103 + 8647027 = 8647130
  • 109 + 8647021 = 8647130
  • 181 + 8646949 = 8647130
  • 241 + 8646889 = 8647130
  • 277 + 8646853 = 8647130

Showing the first eight; more decompositions exist.
