Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744320, here are decompositions:

  • 3 + 8744317 = 8744320
  • 23 + 8744297 = 8744320
  • 59 + 8744261 = 8744320
  • 113 + 8744207 = 8744320
  • 131 + 8744189 = 8744320
  • 191 + 8744129 = 8744320
  • 239 + 8744081 = 8744320
  • 257 + 8744063 = 8744320

Showing the first eight; more decompositions exist.
