Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508716, here are decompositions:

3 + 31508713 = 31508716
59 + 31508657 = 31508716
137 + 31508579 = 31508716
149 + 31508567 = 31508716
167 + 31508549 = 31508716
263 + 31508453 = 31508716
353 + 31508363 = 31508716
557 + 31508159 = 31508716

Showing the first eight; more decompositions exist.
