Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30726, here are decompositions:

13 + 30713 = 30726
19 + 30707 = 30726
23 + 30703 = 30726
29 + 30697 = 30726
37 + 30689 = 30726
83 + 30643 = 30726
89 + 30637 = 30726
149 + 30577 = 30726

Showing the first eight; more decompositions exist.
