Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532700, here are decompositions:

7 + 31532693 = 31532700
13 + 31532687 = 31532700
41 + 31532659 = 31532700
47 + 31532653 = 31532700
61 + 31532639 = 31532700
103 + 31532597 = 31532700
107 + 31532593 = 31532700
113 + 31532587 = 31532700

Showing the first eight; more decompositions exist.
