Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625218, here are decompositions:

31 + 8625187 = 8625218
97 + 8625121 = 8625218
127 + 8625091 = 8625218
211 + 8625007 = 8625218
331 + 8624887 = 8625218
337 + 8624881 = 8625218
397 + 8624821 = 8625218
541 + 8624677 = 8625218

Showing the first eight; more decompositions exist.
