Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502364, here are decompositions:

11 + 31502353 = 31502364
31 + 31502333 = 31502364
53 + 31502311 = 31502364
151 + 31502213 = 31502364
181 + 31502183 = 31502364
233 + 31502131 = 31502364
251 + 31502113 = 31502364
281 + 31502083 = 31502364

Showing the first eight; more decompositions exist.
