Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718678, here are decompositions:

5 + 8718673 = 8718678
29 + 8718649 = 8718678
97 + 8718581 = 8718678
107 + 8718571 = 8718678
139 + 8718539 = 8718678
191 + 8718487 = 8718678
239 + 8718439 = 8718678
251 + 8718427 = 8718678

Showing the first eight; more decompositions exist.
