Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720950, here are decompositions:

  • 3 + 8720947 = 8720950
  • 59 + 8720891 = 8720950
  • 113 + 8720837 = 8720950
  • 131 + 8720819 = 8720950
  • 167 + 8720783 = 8720950
  • 179 + 8720771 = 8720950
  • 257 + 8720693 = 8720950
  • 263 + 8720687 = 8720950

Showing the first eight; more decompositions exist.
