Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624778, here are decompositions:

5 + 8624773 = 8624778
7 + 8624771 = 8624778
61 + 8624717 = 8624778
101 + 8624677 = 8624778
109 + 8624669 = 8624778
157 + 8624621 = 8624778
179 + 8624599 = 8624778
271 + 8624507 = 8624778

Showing the first eight; more decompositions exist.
