Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523152, here are decompositions:

41 + 31523111 = 31523152
53 + 31523099 = 31523152
71 + 31523081 = 31523152
131 + 31523021 = 31523152
149 + 31523003 = 31523152
173 + 31522979 = 31523152
191 + 31522961 = 31523152
251 + 31522901 = 31523152

Showing the first eight; more decompositions exist.
