Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625864, here are decompositions:

  • 11 + 8625853 = 8625864
  • 31 + 8625833 = 8625864
  • 43 + 8625821 = 8625864
  • 53 + 8625811 = 8625864
  • 131 + 8625733 = 8625864
  • 157 + 8625707 = 8625864
  • 223 + 8625641 = 8625864
  • 227 + 8625637 = 8625864

Showing the first eight; more decompositions exist.
