Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608052, here are decompositions:

5 + 31608047 = 31608052
11 + 31608041 = 31608052
23 + 31608029 = 31608052
83 + 31607969 = 31608052
131 + 31607921 = 31608052
149 + 31607903 = 31608052
263 + 31607789 = 31608052
269 + 31607783 = 31608052

Showing the first eight; more decompositions exist.
