Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723658, here are decompositions:

  • 5 + 8723653 = 8723658
  • 19 + 8723639 = 8723658
  • 89 + 8723569 = 8723658
  • 107 + 8723551 = 8723658
  • 127 + 8723531 = 8723658
  • 137 + 8723521 = 8723658
  • 179 + 8723479 = 8723658
  • 199 + 8723459 = 8723658

Showing the first eight; more decompositions exist.
