Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525620, here are decompositions:

11 + 31525609 = 31525620
13 + 31525607 = 31525620
17 + 31525603 = 31525620
19 + 31525601 = 31525620
31 + 31525589 = 31525620
53 + 31525567 = 31525620
67 + 31525553 = 31525620
83 + 31525537 = 31525620

Showing the first eight; more decompositions exist.
