Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559094, here are decompositions:

13 + 31559081 = 31559094
23 + 31559071 = 31559094
43 + 31559051 = 31559094
67 + 31559027 = 31559094
97 + 31558997 = 31559094
101 + 31558993 = 31559094
131 + 31558963 = 31559094
137 + 31558957 = 31559094

Showing the first eight; more decompositions exist.
