Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627162, here are decompositions:

11 + 31627151 = 31627162
29 + 31627133 = 31627162
41 + 31627121 = 31627162
71 + 31627091 = 31627162
89 + 31627073 = 31627162
263 + 31626899 = 31627162
269 + 31626893 = 31627162
293 + 31626869 = 31627162

Showing the first eight; more decompositions exist.
