Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738664, here are decompositions:

5 + 8738659 = 8738664
23 + 8738641 = 8738664
73 + 8738591 = 8738664
83 + 8738581 = 8738664
97 + 8738567 = 8738664
131 + 8738533 = 8738664
157 + 8738507 = 8738664
173 + 8738491 = 8738664

Showing the first eight; more decompositions exist.
