Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506096, here are decompositions:

5 + 31506091 = 31506096
67 + 31506029 = 31506096
103 + 31505993 = 31506096
107 + 31505989 = 31506096
113 + 31505983 = 31506096
137 + 31505959 = 31506096
157 + 31505939 = 31506096
173 + 31505923 = 31506096

Showing the first eight; more decompositions exist.
