Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739570, here are decompositions:

  • 41 + 8739529 = 8739570
  • 67 + 8739503 = 8739570
  • 71 + 8739499 = 8739570
  • 79 + 8739491 = 8739570
  • 89 + 8739481 = 8739570
  • 107 + 8739463 = 8739570
  • 137 + 8739433 = 8739570
  • 139 + 8739431 = 8739570

Showing the first eight; more decompositions exist.
