Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748780, here are decompositions:

  • 13 + 8748767 = 8748780
  • 37 + 8748743 = 8748780
  • 41 + 8748739 = 8748780
  • 67 + 8748713 = 8748780
  • 71 + 8748709 = 8748780
  • 107 + 8748673 = 8748780
  • 127 + 8748653 = 8748780
  • 137 + 8748643 = 8748780

Showing the first eight; more decompositions exist.
