Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568336, here are decompositions:

3 + 31568333 = 31568336
109 + 31568227 = 31568336
139 + 31568197 = 31568336
157 + 31568179 = 31568336
229 + 31568107 = 31568336
277 + 31568059 = 31568336
337 + 31567999 = 31568336
487 + 31567849 = 31568336

Showing the first eight; more decompositions exist.
