Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615092, here are decompositions:

29 + 31615063 = 31615092
31 + 31615061 = 31615092
53 + 31615039 = 31615092
79 + 31615013 = 31615092
139 + 31614953 = 31615092
149 + 31614943 = 31615092
151 + 31614941 = 31615092
163 + 31614929 = 31615092

Showing the first eight; more decompositions exist.
