Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686448, here are decompositions:

  • 79 + 8686369 = 8686448
  • 139 + 8686309 = 8686448
  • 151 + 8686297 = 8686448
  • 157 + 8686291 = 8686448
  • 241 + 8686207 = 8686448
  • 271 + 8686177 = 8686448
  • 307 + 8686141 = 8686448
  • 487 + 8685961 = 8686448

Showing the first eight; more decompositions exist.
