Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658416, here are decompositions:

3 + 8658413 = 8658416
103 + 8658313 = 8658416
127 + 8658289 = 8658416
139 + 8658277 = 8658416
199 + 8658217 = 8658416
223 + 8658193 = 8658416
307 + 8658109 = 8658416
313 + 8658103 = 8658416

Showing the first eight; more decompositions exist.
