Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745224, here are decompositions:

127 + 8745097 = 8745224
157 + 8745067 = 8745224
193 + 8745031 = 8745224
283 + 8744941 = 8745224
307 + 8744917 = 8745224
337 + 8744887 = 8745224
487 + 8744737 = 8745224
541 + 8744683 = 8745224

Showing the first eight; more decompositions exist.
