Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502136, here are decompositions:

5 + 31502131 = 31502136
7 + 31502129 = 31502136
23 + 31502113 = 31502136
37 + 31502099 = 31502136
53 + 31502083 = 31502136
157 + 31501979 = 31502136
179 + 31501957 = 31502136
199 + 31501937 = 31502136

Showing the first eight; more decompositions exist.
