Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729090, here are decompositions:

  • 31 + 8729059 = 8729090
  • 37 + 8729053 = 8729090
  • 103 + 8728987 = 8729090
  • 127 + 8728963 = 8729090
  • 163 + 8728927 = 8729090
  • 193 + 8728897 = 8729090
  • 241 + 8728849 = 8729090
  • 283 + 8728807 = 8729090

Showing the first eight; more decompositions exist.
