Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625170, here are decompositions:

79 + 8625091 = 8625170
97 + 8625073 = 8625170
157 + 8625013 = 8625170
163 + 8625007 = 8625170
241 + 8624929 = 8625170
283 + 8624887 = 8625170
349 + 8624821 = 8625170
397 + 8624773 = 8625170

Showing the first eight; more decompositions exist.
