Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746780, here are decompositions:

  • 23 + 8746757 = 8746780
  • 47 + 8746733 = 8746780
  • 71 + 8746709 = 8746780
  • 83 + 8746697 = 8746780
  • 101 + 8746679 = 8746780
  • 311 + 8746469 = 8746780
  • 353 + 8746427 = 8746780
  • 389 + 8746391 = 8746780

Showing the first eight; more decompositions exist.
