Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516094, here are decompositions:

7 + 31516087 = 31516094
13 + 31516081 = 31516094
67 + 31516027 = 31516094
73 + 31516021 = 31516094
157 + 31515937 = 31516094
163 + 31515931 = 31516094
331 + 31515763 = 31516094
397 + 31515697 = 31516094

Showing the first eight; more decompositions exist.
