Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536032, here are decompositions:

13 + 31536019 = 31536032
211 + 31535821 = 31536032
223 + 31535809 = 31536032
439 + 31535593 = 31536032
613 + 31535419 = 31536032
691 + 31535341 = 31536032
769 + 31535263 = 31536032
859 + 31535173 = 31536032

Showing the first eight; more decompositions exist.
