Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605324, here are decompositions:

5 + 31605319 = 31605324
13 + 31605311 = 31605324
53 + 31605271 = 31605324
61 + 31605263 = 31605324
67 + 31605257 = 31605324
103 + 31605221 = 31605324
181 + 31605143 = 31605324
197 + 31605127 = 31605324

Showing the first eight; more decompositions exist.
