Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502552, here are decompositions:

13 + 31502539 = 31502552
19 + 31502533 = 31502552
181 + 31502371 = 31502552
199 + 31502353 = 31502552
223 + 31502329 = 31502552
241 + 31502311 = 31502552
283 + 31502269 = 31502552
421 + 31502131 = 31502552

Showing the first eight; more decompositions exist.
