Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502116, here are decompositions:

3 + 31502113 = 31502116
17 + 31502099 = 31502116
137 + 31501979 = 31502116
179 + 31501937 = 31502116
293 + 31501823 = 31502116
389 + 31501727 = 31502116
593 + 31501523 = 31502116
683 + 31501433 = 31502116

Showing the first eight; more decompositions exist.
