Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627156, here are decompositions:

5 + 31627151 = 31627156
23 + 31627133 = 31627156
83 + 31627073 = 31627156
149 + 31627007 = 31627156
179 + 31626977 = 31627156
257 + 31626899 = 31627156
263 + 31626893 = 31627156
317 + 31626839 = 31627156

Showing the first eight; more decompositions exist.
