Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625668, here are decompositions:

19 + 8625649 = 8625668
31 + 8625637 = 8625668
109 + 8625559 = 8625668
127 + 8625541 = 8625668
151 + 8625517 = 8625668
367 + 8625301 = 8625668
379 + 8625289 = 8625668
421 + 8625247 = 8625668

Showing the first eight; more decompositions exist.
