Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559064, here are decompositions:

13 + 31559051 = 31559064
37 + 31559027 = 31559064
67 + 31558997 = 31559064
71 + 31558993 = 31559064
101 + 31558963 = 31559064
107 + 31558957 = 31559064
137 + 31558927 = 31559064
167 + 31558897 = 31559064

Showing the first eight; more decompositions exist.
