Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537094, here are decompositions:

7 + 31537087 = 31537094
67 + 31537027 = 31537094
103 + 31536991 = 31537094
151 + 31536943 = 31537094
157 + 31536937 = 31537094
223 + 31536871 = 31537094
271 + 31536823 = 31537094
397 + 31536697 = 31537094

Showing the first eight; more decompositions exist.
