Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627074, here are decompositions:

5 + 31627069 = 31627074
23 + 31627051 = 31627074
41 + 31627033 = 31627074
47 + 31627027 = 31627074
67 + 31627007 = 31627074
97 + 31626977 = 31627074
107 + 31626967 = 31627074
131 + 31626943 = 31627074

Showing the first eight; more decompositions exist.
