Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42646, here are decompositions:

3 + 42643 = 42646
5 + 42641 = 42646
89 + 42557 = 42646
113 + 42533 = 42646
137 + 42509 = 42646
173 + 42473 = 42646
179 + 42467 = 42646
239 + 42407 = 42646

Showing the first eight; more decompositions exist.
