Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627150, here are decompositions:

17 + 31627133 = 31627150
29 + 31627121 = 31627150
59 + 31627091 = 31627150
173 + 31626977 = 31627150
251 + 31626899 = 31627150
257 + 31626893 = 31627150
281 + 31626869 = 31627150
293 + 31626857 = 31627150

Showing the first eight; more decompositions exist.
