Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30994, here are decompositions:

11 + 30983 = 30994
17 + 30977 = 30994
23 + 30971 = 30994
53 + 30941 = 30994
83 + 30911 = 30994
101 + 30893 = 30994
113 + 30881 = 30994
191 + 30803 = 30994

Showing the first eight; more decompositions exist.
