Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745426, here are decompositions:

7 + 8745419 = 8745426
59 + 8745367 = 8745426
73 + 8745353 = 8745426
83 + 8745343 = 8745426
97 + 8745329 = 8745426
127 + 8745299 = 8745426
199 + 8745227 = 8745426
223 + 8745203 = 8745426

Showing the first eight; more decompositions exist.
