Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729930, here are decompositions:

  • 7 + 8729923 = 8729930
  • 43 + 8729887 = 8729930
  • 61 + 8729869 = 8729930
  • 109 + 8729821 = 8729930
  • 163 + 8729767 = 8729930
  • 241 + 8729689 = 8729930
  • 271 + 8729659 = 8729930
  • 283 + 8729647 = 8729930

Showing the first eight; more decompositions exist.
