Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502058, here are decompositions:

79 + 31501979 = 31502058
101 + 31501957 = 31502058
151 + 31501907 = 31502058
179 + 31501879 = 31502058
197 + 31501861 = 31502058
227 + 31501831 = 31502058
239 + 31501819 = 31502058
251 + 31501807 = 31502058

Showing the first eight; more decompositions exist.
