Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627050, here are decompositions:

17 + 31627033 = 31627050
23 + 31627027 = 31627050
43 + 31627007 = 31627050
71 + 31626979 = 31627050
73 + 31626977 = 31627050
83 + 31626967 = 31627050
107 + 31626943 = 31627050
151 + 31626899 = 31627050

Showing the first eight; more decompositions exist.
