Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30984, here are decompositions:

7 + 30977 = 30984
13 + 30971 = 30984
43 + 30941 = 30984
47 + 30937 = 30984
53 + 30931 = 30984
73 + 30911 = 30984
103 + 30881 = 30984
113 + 30871 = 30984

Showing the first eight; more decompositions exist.
