Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678938, here are decompositions:

5 + 8678933 = 8678938
11 + 8678927 = 8678938
179 + 8678759 = 8678938
197 + 8678741 = 8678938
239 + 8678699 = 8678938
269 + 8678669 = 8678938
419 + 8678519 = 8678938
431 + 8678507 = 8678938

Showing the first eight; more decompositions exist.
