Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625370, here are decompositions:

11 + 8625359 = 8625370
53 + 8625317 = 8625370
59 + 8625311 = 8625370
107 + 8625263 = 8625370
137 + 8625233 = 8625370
167 + 8625203 = 8625370
179 + 8625191 = 8625370
197 + 8625173 = 8625370

Showing the first eight; more decompositions exist.
