Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624730, here are decompositions:

13 + 8624717 = 8624730
17 + 8624713 = 8624730
53 + 8624677 = 8624730
61 + 8624669 = 8624730
97 + 8624633 = 8624730
109 + 8624621 = 8624730
113 + 8624617 = 8624730
131 + 8624599 = 8624730

Showing the first eight; more decompositions exist.
