Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634778, here are decompositions:

  • 11 + 8634767 = 8634778
  • 17 + 8634761 = 8634778
  • 101 + 8634677 = 8634778
  • 107 + 8634671 = 8634778
  • 149 + 8634629 = 8634778
  • 197 + 8634581 = 8634778
  • 227 + 8634551 = 8634778
  • 239 + 8634539 = 8634778

Showing the first eight; more decompositions exist.
