Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625242, here are decompositions:

13 + 8625229 = 8625242
151 + 8625091 = 8625242
229 + 8625013 = 8625242
313 + 8624929 = 8625242
421 + 8624821 = 8625242
643 + 8624599 = 8625242
739 + 8624503 = 8625242
859 + 8624383 = 8625242

Showing the first eight; more decompositions exist.
