Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621304, here are decompositions:

5 + 8621299 = 8621304
23 + 8621281 = 8621304
61 + 8621243 = 8621304
67 + 8621237 = 8621304
103 + 8621201 = 8621304
151 + 8621153 = 8621304
157 + 8621147 = 8621304
227 + 8621077 = 8621304

Showing the first eight; more decompositions exist.
