Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594434, here are decompositions:

5 + 31594429 = 31594434
13 + 31594421 = 31594434
41 + 31594393 = 31594434
61 + 31594373 = 31594434
83 + 31594351 = 31594434
101 + 31594333 = 31594434
103 + 31594331 = 31594434
163 + 31594271 = 31594434

Showing the first eight; more decompositions exist.
