Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738886, here are decompositions:

5 + 8738881 = 8738886
43 + 8738843 = 8738886
47 + 8738839 = 8738886
73 + 8738813 = 8738886
103 + 8738783 = 8738886
127 + 8738759 = 8738886
157 + 8738729 = 8738886
173 + 8738713 = 8738886

Showing the first eight; more decompositions exist.
