Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532600, here are decompositions:

3 + 31532597 = 31532600
7 + 31532593 = 31532600
13 + 31532587 = 31532600
19 + 31532581 = 31532600
61 + 31532539 = 31532600
79 + 31532521 = 31532600
103 + 31532497 = 31532600
163 + 31532437 = 31532600

Showing the first eight; more decompositions exist.
