Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594524, here are decompositions:

23 + 31594501 = 31594524
61 + 31594463 = 31594524
103 + 31594421 = 31594524
131 + 31594393 = 31594524
151 + 31594373 = 31594524
173 + 31594351 = 31594524
191 + 31594333 = 31594524
193 + 31594331 = 31594524

Showing the first eight; more decompositions exist.
