Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568232, here are decompositions:

5 + 31568227 = 31568232
11 + 31568221 = 31568232
29 + 31568203 = 31568232
53 + 31568179 = 31568232
103 + 31568129 = 31568232
109 + 31568123 = 31568232
149 + 31568083 = 31568232
173 + 31568059 = 31568232

Showing the first eight; more decompositions exist.
