Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603518, here are decompositions:

29 + 8603489 = 8603518
41 + 8603477 = 8603518
47 + 8603471 = 8603518
89 + 8603429 = 8603518
137 + 8603381 = 8603518
149 + 8603369 = 8603518
251 + 8603267 = 8603518
269 + 8603249 = 8603518

Showing the first eight; more decompositions exist.
