Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77664, here are decompositions:

  • 5 + 77659 = 77664
  • 17 + 77647 = 77664
  • 23 + 77641 = 77664
  • 43 + 77621 = 77664
  • 47 + 77617 = 77664
  • 53 + 77611 = 77664
  • 73 + 77591 = 77664
  • 101 + 77563 = 77664

Showing the first eight; more decompositions exist.
