Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613438, here are decompositions:

11 + 8613427 = 8613438
17 + 8613421 = 8613438
47 + 8613391 = 8613438
59 + 8613379 = 8613438
89 + 8613349 = 8613438
109 + 8613329 = 8613438
139 + 8613299 = 8613438
157 + 8613281 = 8613438

Showing the first eight; more decompositions exist.
