Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30964, here are decompositions:

23 + 30941 = 30964
53 + 30911 = 30964
71 + 30893 = 30964
83 + 30881 = 30964
113 + 30851 = 30964
191 + 30773 = 30964
251 + 30713 = 30964
257 + 30707 = 30964

Showing the first eight; more decompositions exist.
