Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678788, here are decompositions:

5 + 8678783 = 8678788
11 + 8678777 = 8678788
29 + 8678759 = 8678788
47 + 8678741 = 8678788
89 + 8678699 = 8678788
149 + 8678639 = 8678788
269 + 8678519 = 8678788
281 + 8678507 = 8678788

Showing the first eight; more decompositions exist.
