Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675784, here are decompositions:

  • 17 + 8675767 = 8675784
  • 41 + 8675743 = 8675784
  • 107 + 8675677 = 8675784
  • 113 + 8675671 = 8675784
  • 163 + 8675621 = 8675784
  • 193 + 8675591 = 8675784
  • 211 + 8675573 = 8675784
  • 263 + 8675521 = 8675784

Showing the first eight; more decompositions exist.
