Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559832, here are decompositions:

11 + 31559821 = 31559832
19 + 31559813 = 31559832
23 + 31559809 = 31559832
61 + 31559771 = 31559832
113 + 31559719 = 31559832
151 + 31559681 = 31559832
173 + 31559659 = 31559832
179 + 31559653 = 31559832

Showing the first eight; more decompositions exist.
