Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31150, here are decompositions:

3 + 31147 = 31150
11 + 31139 = 31150
29 + 31121 = 31150
59 + 31091 = 31150
71 + 31079 = 31150
131 + 31019 = 31150
137 + 31013 = 31150
167 + 30983 = 31150

Showing the first eight; more decompositions exist.
