Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30814, here are decompositions:

5 + 30809 = 30814
11 + 30803 = 30814
41 + 30773 = 30814
101 + 30713 = 30814
107 + 30707 = 30814
137 + 30677 = 30814
257 + 30557 = 30814
317 + 30497 = 30814

Showing the first eight; more decompositions exist.
