Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532608, here are decompositions:

11 + 31532597 = 31532608
101 + 31532507 = 31532608
131 + 31532477 = 31532608
179 + 31532429 = 31532608
269 + 31532339 = 31532608
347 + 31532261 = 31532608
389 + 31532219 = 31532608
467 + 31532141 = 31532608

Showing the first eight; more decompositions exist.
