Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31948, here are decompositions:

41 + 31907 = 31948
89 + 31859 = 31948
101 + 31847 = 31948
131 + 31817 = 31948
149 + 31799 = 31948
179 + 31769 = 31948
197 + 31751 = 31948
227 + 31721 = 31948

Showing the first eight; more decompositions exist.
