Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532556, here are decompositions:

5 + 31532551 = 31532556
17 + 31532539 = 31532556
59 + 31532497 = 31532556
67 + 31532489 = 31532556
79 + 31532477 = 31532556
127 + 31532429 = 31532556
227 + 31532329 = 31532556
233 + 31532323 = 31532556

Showing the first eight; more decompositions exist.
