Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523526, here are decompositions:

5 + 31523521 = 31523526
53 + 31523473 = 31523526
59 + 31523467 = 31523526
107 + 31523419 = 31523526
127 + 31523399 = 31523526
179 + 31523347 = 31523526
197 + 31523329 = 31523526
233 + 31523293 = 31523526

Showing the first eight; more decompositions exist.
