Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594968, here are decompositions:

5 + 31594963 = 31594968
7 + 31594961 = 31594968
37 + 31594931 = 31594968
61 + 31594907 = 31594968
101 + 31594867 = 31594968
107 + 31594861 = 31594968
157 + 31594811 = 31594968
199 + 31594769 = 31594968

Showing the first eight; more decompositions exist.
