Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532562, here are decompositions:

11 + 31532551 = 31532562
23 + 31532539 = 31532562
41 + 31532521 = 31532562
73 + 31532489 = 31532562
223 + 31532339 = 31532562
233 + 31532329 = 31532562
239 + 31532323 = 31532562
283 + 31532279 = 31532562

Showing the first eight; more decompositions exist.
