Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594482, here are decompositions:

19 + 31594463 = 31594482
53 + 31594429 = 31594482
61 + 31594421 = 31594482
83 + 31594399 = 31594482
89 + 31594393 = 31594482
109 + 31594373 = 31594482
131 + 31594351 = 31594482
149 + 31594333 = 31594482

Showing the first eight; more decompositions exist.
