Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738808, here are decompositions:

7 + 8738801 = 8738808
41 + 8738767 = 8738808
79 + 8738729 = 8738808
97 + 8738711 = 8738808
101 + 8738707 = 8738808
137 + 8738671 = 8738808
149 + 8738659 = 8738808
167 + 8738641 = 8738808

Showing the first eight; more decompositions exist.
