Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594162, here are decompositions:

3 + 31594159 = 31594162
11 + 31594151 = 31594162
29 + 31594133 = 31594162
101 + 31594061 = 31594162
113 + 31594049 = 31594162
179 + 31593983 = 31594162
293 + 31593869 = 31594162
443 + 31593719 = 31594162

Showing the first eight; more decompositions exist.
