Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631338, here are decompositions:

7 + 8631331 = 8631338
19 + 8631319 = 8631338
31 + 8631307 = 8631338
61 + 8631277 = 8631338
109 + 8631229 = 8631338
139 + 8631199 = 8631338
229 + 8631109 = 8631338
241 + 8631097 = 8631338

Showing the first eight; more decompositions exist.
