Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738816, here are decompositions:

3 + 8738813 = 8738816
7 + 8738809 = 8738816
103 + 8738713 = 8738816
109 + 8738707 = 8738816
157 + 8738659 = 8738816
277 + 8738539 = 8738816
283 + 8738533 = 8738816
367 + 8738449 = 8738816

Showing the first eight; more decompositions exist.
