Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568132, here are decompositions:

3 + 31568129 = 31568132
61 + 31568071 = 31568132
73 + 31568059 = 31568132
151 + 31567981 = 31568132
283 + 31567849 = 31568132
313 + 31567819 = 31568132
433 + 31567699 = 31568132
439 + 31567693 = 31568132

Showing the first eight; more decompositions exist.
