Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594380, here are decompositions:

7 + 31594373 = 31594380
29 + 31594351 = 31594380
47 + 31594333 = 31594380
71 + 31594309 = 31594380
107 + 31594273 = 31594380
109 + 31594271 = 31594380
229 + 31594151 = 31594380
283 + 31594097 = 31594380

Showing the first eight; more decompositions exist.
