Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532828, here are decompositions:

79 + 31532749 = 31532828
241 + 31532587 = 31532828
277 + 31532551 = 31532828
307 + 31532521 = 31532828
331 + 31532497 = 31532828
487 + 31532341 = 31532828
499 + 31532329 = 31532828
601 + 31532227 = 31532828

Showing the first eight; more decompositions exist.
