Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532694, here are decompositions:

7 + 31532687 = 31532694
41 + 31532653 = 31532694
97 + 31532597 = 31532694
101 + 31532593 = 31532694
107 + 31532587 = 31532694
113 + 31532581 = 31532694
173 + 31532521 = 31532694
197 + 31532497 = 31532694

Showing the first eight; more decompositions exist.
