Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560032, here are decompositions:

3 + 31560029 = 31560032
13 + 31560019 = 31560032
43 + 31559989 = 31560032
181 + 31559851 = 31560032
199 + 31559833 = 31560032
211 + 31559821 = 31560032
223 + 31559809 = 31560032
313 + 31559719 = 31560032

Showing the first eight; more decompositions exist.
