Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30946, here are decompositions:

5 + 30941 = 30946
53 + 30893 = 30946
107 + 30839 = 30946
137 + 30809 = 30946
173 + 30773 = 30946
233 + 30713 = 30946
239 + 30707 = 30946
257 + 30689 = 30946

Showing the first eight; more decompositions exist.
