Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620232, here are decompositions:

3 + 31620229 = 31620232
23 + 31620209 = 31620232
29 + 31620203 = 31620232
41 + 31620191 = 31620232
101 + 31620131 = 31620232
173 + 31620059 = 31620232
239 + 31619993 = 31620232
251 + 31619981 = 31620232

Showing the first eight; more decompositions exist.
