Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595040, here are decompositions:

19 + 31595021 = 31595040
31 + 31595009 = 31595040
41 + 31594999 = 31595040
53 + 31594987 = 31595040
79 + 31594961 = 31595040
109 + 31594931 = 31595040
137 + 31594903 = 31595040
157 + 31594883 = 31595040

Showing the first eight; more decompositions exist.
