Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559016, here are decompositions:

19 + 31558997 = 31559016
23 + 31558993 = 31559016
43 + 31558973 = 31559016
53 + 31558963 = 31559016
59 + 31558957 = 31559016
89 + 31558927 = 31559016
157 + 31558859 = 31559016
173 + 31558843 = 31559016

Showing the first eight; more decompositions exist.
