Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502316, here are decompositions:

5 + 31502311 = 31502316
29 + 31502287 = 31502316
37 + 31502279 = 31502316
47 + 31502269 = 31502316
73 + 31502243 = 31502316
103 + 31502213 = 31502316
127 + 31502189 = 31502316
233 + 31502083 = 31502316

Showing the first eight; more decompositions exist.
