Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532696, here are decompositions:

3 + 31532693 = 31532696
37 + 31532659 = 31532696
43 + 31532653 = 31532696
103 + 31532593 = 31532696
109 + 31532587 = 31532696
157 + 31532539 = 31532696
199 + 31532497 = 31532696
367 + 31532329 = 31532696

Showing the first eight; more decompositions exist.
