Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738688, here are decompositions:

17 + 8738671 = 8738688
29 + 8738659 = 8738688
47 + 8738641 = 8738688
97 + 8738591 = 8738688
107 + 8738581 = 8738688
109 + 8738579 = 8738688
149 + 8738539 = 8738688
181 + 8738507 = 8738688

Showing the first eight; more decompositions exist.
