Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621346, here are decompositions:

7 + 8621339 = 8621346
37 + 8621309 = 8621346
47 + 8621299 = 8621346
103 + 8621243 = 8621346
109 + 8621237 = 8621346
137 + 8621209 = 8621346
157 + 8621189 = 8621346
163 + 8621183 = 8621346

Showing the first eight; more decompositions exist.
