Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723550, here are decompositions:

  • 19 + 8723531 = 8723550
  • 29 + 8723521 = 8723550
  • 53 + 8723497 = 8723550
  • 67 + 8723483 = 8723550
  • 71 + 8723479 = 8723550
  • 109 + 8723441 = 8723550
  • 113 + 8723437 = 8723550
  • 127 + 8723423 = 8723550

Showing the first eight; more decompositions exist.
