Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657722, here are decompositions:

  • 23 + 8657699 = 8657722
  • 41 + 8657681 = 8657722
  • 71 + 8657651 = 8657722
  • 83 + 8657639 = 8657722
  • 89 + 8657633 = 8657722
  • 389 + 8657333 = 8657722
  • 431 + 8657291 = 8657722
  • 599 + 8657123 = 8657722

Showing the first eight; more decompositions exist.
