Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657766, here are decompositions:

  • 43 + 8657723 = 8657766
  • 67 + 8657699 = 8657766
  • 79 + 8657687 = 8657766
  • 127 + 8657639 = 8657766
  • 137 + 8657629 = 8657766
  • 197 + 8657569 = 8657766
  • 199 + 8657567 = 8657766
  • 233 + 8657533 = 8657766

Showing the first eight; more decompositions exist.
