Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627116, here are decompositions:

43 + 31627073 = 31627116
47 + 31627069 = 31627116
83 + 31627033 = 31627116
89 + 31627027 = 31627116
109 + 31627007 = 31627116
137 + 31626979 = 31627116
139 + 31626977 = 31627116
149 + 31626967 = 31627116

Showing the first eight; more decompositions exist.
