Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30910, here are decompositions:

17 + 30893 = 30910
29 + 30881 = 30910
41 + 30869 = 30910
59 + 30851 = 30910
71 + 30839 = 30910
101 + 30809 = 30910
107 + 30803 = 30910
137 + 30773 = 30910

Showing the first eight; more decompositions exist.
