Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523536, here are decompositions:

59 + 31523477 = 31523536
137 + 31523399 = 31523536
227 + 31523309 = 31523536
257 + 31523279 = 31523536
269 + 31523267 = 31523536
293 + 31523243 = 31523536
509 + 31523027 = 31523536
557 + 31522979 = 31523536

Showing the first eight; more decompositions exist.
