Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508094, here are decompositions:

11 + 31508083 = 31508094
17 + 31508077 = 31508094
67 + 31508027 = 31508094
103 + 31507991 = 31508094
113 + 31507981 = 31508094
173 + 31507921 = 31508094
181 + 31507913 = 31508094
193 + 31507901 = 31508094

Showing the first eight; more decompositions exist.
