Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65678, here are decompositions:

31 + 65647 = 65678
61 + 65617 = 65678
79 + 65599 = 65678
97 + 65581 = 65678
127 + 65551 = 65678
139 + 65539 = 65678
157 + 65521 = 65678
181 + 65497 = 65678

Showing the first eight; more decompositions exist.
