Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594166, here are decompositions:

3 + 31594163 = 31594166
7 + 31594159 = 31594166
103 + 31594063 = 31594166
127 + 31594039 = 31594166
223 + 31593943 = 31594166
229 + 31593937 = 31594166
379 + 31593787 = 31594166
463 + 31593703 = 31594166

Showing the first eight; more decompositions exist.
