Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523230, here are decompositions:

3 + 31523227 = 31523230
23 + 31523207 = 31523230
29 + 31523201 = 31523230
131 + 31523099 = 31523230
149 + 31523081 = 31523230
227 + 31523003 = 31523230
251 + 31522979 = 31523230
269 + 31522961 = 31523230

Showing the first eight; more decompositions exist.
