Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625220, here are decompositions:

17 + 8625203 = 8625220
29 + 8625191 = 8625220
47 + 8625173 = 8625220
89 + 8625131 = 8625220
101 + 8625119 = 8625220
137 + 8625083 = 8625220
167 + 8625053 = 8625220
239 + 8624981 = 8625220

Showing the first eight; more decompositions exist.
