Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532996, here are decompositions:

37 + 31532959 = 31532996
73 + 31532923 = 31532996
97 + 31532899 = 31532996
163 + 31532833 = 31532996
337 + 31532659 = 31532996
409 + 31532587 = 31532996
457 + 31532539 = 31532996
499 + 31532497 = 31532996

Showing the first eight; more decompositions exist.
