Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31030, here are decompositions:

11 + 31019 = 31030
17 + 31013 = 31030
47 + 30983 = 31030
53 + 30977 = 31030
59 + 30971 = 31030
89 + 30941 = 31030
137 + 30893 = 31030
149 + 30881 = 31030

Showing the first eight; more decompositions exist.
