Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738448, here are decompositions:

11 + 8738437 = 8738448
41 + 8738407 = 8738448
71 + 8738377 = 8738448
97 + 8738351 = 8738448
109 + 8738339 = 8738448
149 + 8738299 = 8738448
167 + 8738281 = 8738448
239 + 8738209 = 8738448

Showing the first eight; more decompositions exist.
