Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631874, here are decompositions:

  • 23 + 8631851 = 8631874
  • 71 + 8631803 = 8631874
  • 131 + 8631743 = 8631874
  • 137 + 8631737 = 8631874
  • 257 + 8631617 = 8631874
  • 263 + 8631611 = 8631874
  • 683 + 8631191 = 8631874
  • 857 + 8631017 = 8631874

Showing the first eight; more decompositions exist.
