Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78724, here are decompositions:

3 + 78721 = 78724
11 + 78713 = 78724
17 + 78707 = 78724
71 + 78653 = 78724
101 + 78623 = 78724
131 + 78593 = 78724
227 + 78497 = 78724
257 + 78467 = 78724

Showing the first eight; more decompositions exist.
