Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722650, here are decompositions:

  • 7 + 8722643 = 8722650
  • 19 + 8722631 = 8722650
  • 29 + 8722621 = 8722650
  • 37 + 8722613 = 8722650
  • 43 + 8722607 = 8722650
  • 47 + 8722603 = 8722650
  • 109 + 8722541 = 8722650
  • 151 + 8722499 = 8722650

Showing the first eight; more decompositions exist.
