Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532508, here are decompositions:

11 + 31532497 = 31532508
19 + 31532489 = 31532508
31 + 31532477 = 31532508
71 + 31532437 = 31532508
79 + 31532429 = 31532508
107 + 31532401 = 31532508
167 + 31532341 = 31532508
179 + 31532329 = 31532508

Showing the first eight; more decompositions exist.
