Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738670, here are decompositions:

11 + 8738659 = 8738670
29 + 8738641 = 8738670
79 + 8738591 = 8738670
89 + 8738581 = 8738670
103 + 8738567 = 8738670
131 + 8738539 = 8738670
137 + 8738533 = 8738670
163 + 8738507 = 8738670

Showing the first eight; more decompositions exist.
