Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594470, here are decompositions:

7 + 31594463 = 31594470
41 + 31594429 = 31594470
71 + 31594399 = 31594470
97 + 31594373 = 31594470
137 + 31594333 = 31594470
139 + 31594331 = 31594470
197 + 31594273 = 31594470
199 + 31594271 = 31594470

Showing the first eight; more decompositions exist.
