Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625266, here are decompositions:

3 + 8625263 = 8625266
19 + 8625247 = 8625266
37 + 8625229 = 8625266
79 + 8625187 = 8625266
193 + 8625073 = 8625266
313 + 8624953 = 8625266
337 + 8624929 = 8625266
379 + 8624887 = 8625266

Showing the first eight; more decompositions exist.
