Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78646, here are decompositions:

3 + 78643 = 78646
23 + 78623 = 78646
53 + 78593 = 78646
107 + 78539 = 78646
137 + 78509 = 78646
149 + 78497 = 78646
167 + 78479 = 78646
179 + 78467 = 78646

Showing the first eight; more decompositions exist.
