Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532664, here are decompositions:

5 + 31532659 = 31532664
11 + 31532653 = 31532664
67 + 31532597 = 31532664
71 + 31532593 = 31532664
83 + 31532581 = 31532664
113 + 31532551 = 31532664
157 + 31532507 = 31532664
167 + 31532497 = 31532664

Showing the first eight; more decompositions exist.
