Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532598, here are decompositions:

5 + 31532593 = 31532598
11 + 31532587 = 31532598
17 + 31532581 = 31532598
47 + 31532551 = 31532598
59 + 31532539 = 31532598
101 + 31532497 = 31532598
109 + 31532489 = 31532598
197 + 31532401 = 31532598

Showing the first eight; more decompositions exist.
