Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532708, here are decompositions:

127 + 31532581 = 31532708
157 + 31532551 = 31532708
211 + 31532497 = 31532708
271 + 31532437 = 31532708
307 + 31532401 = 31532708
367 + 31532341 = 31532708
379 + 31532329 = 31532708
439 + 31532269 = 31532708

Showing the first eight; more decompositions exist.
