Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31074, here are decompositions:

5 + 31069 = 31074
11 + 31063 = 31074
23 + 31051 = 31074
41 + 31033 = 31074
61 + 31013 = 31074
97 + 30977 = 31074
103 + 30971 = 31074
137 + 30937 = 31074

Showing the first eight; more decompositions exist.
