Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523136, here are decompositions:

5 + 31523131 = 31523136
17 + 31523119 = 31523136
23 + 31523113 = 31523136
37 + 31523099 = 31523136
83 + 31523053 = 31523136
109 + 31523027 = 31523136
149 + 31522987 = 31523136
157 + 31522979 = 31523136

Showing the first eight; more decompositions exist.
