Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536824, here are decompositions:

3 + 31536821 = 31536824
31 + 31536793 = 31536824
127 + 31536697 = 31536824
211 + 31536613 = 31536824
421 + 31536403 = 31536824
433 + 31536391 = 31536824
463 + 31536361 = 31536824
601 + 31536223 = 31536824

Showing the first eight; more decompositions exist.
