Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612778, here are decompositions:

  • 11 + 8612767 = 8612778
  • 47 + 8612731 = 8612778
  • 67 + 8612711 = 8612778
  • 71 + 8612707 = 8612778
  • 89 + 8612689 = 8612778
  • 107 + 8612671 = 8612778
  • 137 + 8612641 = 8612778
  • 149 + 8612629 = 8612778

Showing the first eight; more decompositions exist.
