Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738818, here are decompositions:

5 + 8738813 = 8738818
17 + 8738801 = 8738818
59 + 8738759 = 8738818
89 + 8738729 = 8738818
107 + 8738711 = 8738818
227 + 8738591 = 8738818
239 + 8738579 = 8738818
251 + 8738567 = 8738818

Showing the first eight; more decompositions exist.
