Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616438, here are decompositions:

7 + 8616431 = 8616438
31 + 8616407 = 8616438
41 + 8616397 = 8616438
59 + 8616379 = 8616438
67 + 8616371 = 8616438
101 + 8616337 = 8616438
139 + 8616299 = 8616438
157 + 8616281 = 8616438

Showing the first eight; more decompositions exist.
