Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723816, here are decompositions:

  • 109 + 8723707 = 8723816
  • 139 + 8723677 = 8723816
  • 163 + 8723653 = 8723816
  • 223 + 8723593 = 8723816
  • 337 + 8723479 = 8723816
  • 379 + 8723437 = 8723816
  • 397 + 8723419 = 8723816
  • 457 + 8723359 = 8723816

Showing the first eight; more decompositions exist.
