Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737780, here are decompositions:

  • 17 + 8737763 = 8737780
  • 71 + 8737709 = 8737780
  • 83 + 8737697 = 8737780
  • 113 + 8737667 = 8737780
  • 197 + 8737583 = 8737780
  • 251 + 8737529 = 8737780
  • 257 + 8737523 = 8737780
  • 347 + 8737433 = 8737780

Showing the first eight; more decompositions exist.
