Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626232, here are decompositions:

3 + 31626229 = 31626232
23 + 31626209 = 31626232
41 + 31626191 = 31626232
101 + 31626131 = 31626232
179 + 31626053 = 31626232
191 + 31626041 = 31626232
251 + 31625981 = 31626232
263 + 31625969 = 31626232

Showing the first eight; more decompositions exist.
