Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618316, here are decompositions:

19 + 8618297 = 8618316
23 + 8618293 = 8618316
29 + 8618287 = 8618316
43 + 8618273 = 8618316
59 + 8618257 = 8618316
73 + 8618243 = 8618316
79 + 8618237 = 8618316
103 + 8618213 = 8618316

Showing the first eight; more decompositions exist.
