Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523162, here are decompositions:

19 + 31523143 = 31523162
31 + 31523131 = 31523162
43 + 31523119 = 31523162
109 + 31523053 = 31523162
211 + 31522951 = 31523162
499 + 31522663 = 31523162
571 + 31522591 = 31523162
613 + 31522549 = 31523162

Showing the first eight; more decompositions exist.
