Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532634, here are decompositions:

37 + 31532597 = 31532634
41 + 31532593 = 31532634
47 + 31532587 = 31532634
53 + 31532581 = 31532634
61 + 31532573 = 31532634
83 + 31532551 = 31532634
113 + 31532521 = 31532634
127 + 31532507 = 31532634

Showing the first eight; more decompositions exist.
