Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749470, here are decompositions:

  • 13 + 8749457 = 8749470
  • 19 + 8749451 = 8749470
  • 31 + 8749439 = 8749470
  • 47 + 8749423 = 8749470
  • 53 + 8749417 = 8749470
  • 113 + 8749357 = 8749470
  • 127 + 8749343 = 8749470
  • 139 + 8749331 = 8749470

Showing the first eight; more decompositions exist.
