Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523646, here are decompositions:

13 + 31523633 = 31523646
47 + 31523599 = 31523646
67 + 31523579 = 31523646
107 + 31523539 = 31523646
109 + 31523537 = 31523646
173 + 31523473 = 31523646
179 + 31523467 = 31523646
227 + 31523419 = 31523646

Showing the first eight; more decompositions exist.
