Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520094, here are decompositions:

5 + 31520089 = 31520094
83 + 31520011 = 31520094
107 + 31519987 = 31520094
157 + 31519937 = 31520094
167 + 31519927 = 31520094
251 + 31519843 = 31520094
257 + 31519837 = 31520094
271 + 31519823 = 31520094

Showing the first eight; more decompositions exist.
