Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502086, here are decompositions:

3 + 31502083 = 31502086
107 + 31501979 = 31502086
149 + 31501937 = 31502086
173 + 31501913 = 31502086
179 + 31501907 = 31502086
263 + 31501823 = 31502086
359 + 31501727 = 31502086
467 + 31501619 = 31502086

Showing the first eight; more decompositions exist.
