Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720694, here are decompositions:

  • 5 + 8720689 = 8720694
  • 7 + 8720687 = 8720694
  • 13 + 8720681 = 8720694
  • 23 + 8720671 = 8720694
  • 67 + 8720627 = 8720694
  • 71 + 8720623 = 8720694
  • 97 + 8720597 = 8720694
  • 113 + 8720581 = 8720694

Showing the first eight; more decompositions exist.
