Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30736, here are decompositions:

23 + 30713 = 30736
29 + 30707 = 30736
47 + 30689 = 30736
59 + 30677 = 30736
179 + 30557 = 30736
197 + 30539 = 30736
227 + 30509 = 30736
239 + 30497 = 30736

Showing the first eight; more decompositions exist.
