Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532604, here are decompositions:

7 + 31532597 = 31532604
11 + 31532593 = 31532604
17 + 31532587 = 31532604
23 + 31532581 = 31532604
31 + 31532573 = 31532604
53 + 31532551 = 31532604
83 + 31532521 = 31532604
97 + 31532507 = 31532604

Showing the first eight; more decompositions exist.
