Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31222, here are decompositions:

3 + 31219 = 31222
29 + 31193 = 31222
41 + 31181 = 31222
71 + 31151 = 31222
83 + 31139 = 31222
101 + 31121 = 31222
131 + 31091 = 31222
239 + 30983 = 31222

Showing the first eight; more decompositions exist.
