Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625216, here are decompositions:

13 + 8625203 = 8625216
29 + 8625187 = 8625216
43 + 8625173 = 8625216
97 + 8625119 = 8625216
139 + 8625077 = 8625216
157 + 8625059 = 8625216
163 + 8625053 = 8625216
263 + 8624953 = 8625216

Showing the first eight; more decompositions exist.
