Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594086, here are decompositions:

5 + 31594081 = 31594086
23 + 31594063 = 31594086
37 + 31594049 = 31594086
47 + 31594039 = 31594086
103 + 31593983 = 31594086
127 + 31593959 = 31594086
149 + 31593937 = 31594086
367 + 31593719 = 31594086

Showing the first eight; more decompositions exist.
