Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568234, here are decompositions:

7 + 31568227 = 31568234
13 + 31568221 = 31568234
31 + 31568203 = 31568234
37 + 31568197 = 31568234
127 + 31568107 = 31568234
151 + 31568083 = 31568234
163 + 31568071 = 31568234
193 + 31568041 = 31568234

Showing the first eight; more decompositions exist.
