Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531652, here are decompositions:

3 + 31531649 = 31531652
13 + 31531639 = 31531652
73 + 31531579 = 31531652
181 + 31531471 = 31531652
199 + 31531453 = 31531652
283 + 31531369 = 31531652
349 + 31531303 = 31531652
379 + 31531273 = 31531652

Showing the first eight; more decompositions exist.
