Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31210, here are decompositions:

17 + 31193 = 31210
29 + 31181 = 31210
59 + 31151 = 31210
71 + 31139 = 31210
89 + 31121 = 31210
131 + 31079 = 31210
191 + 31019 = 31210
197 + 31013 = 31210

Showing the first eight; more decompositions exist.
