Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625212, here are decompositions:

139 + 8625073 = 8625212
199 + 8625013 = 8625212
283 + 8624929 = 8625212
331 + 8624881 = 8625212
439 + 8624773 = 8625212
499 + 8624713 = 8625212
613 + 8624599 = 8625212
709 + 8624503 = 8625212

Showing the first eight; more decompositions exist.
