Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584234, here are decompositions:

23 + 31584211 = 31584234
37 + 31584197 = 31584234
41 + 31584193 = 31584234
43 + 31584191 = 31584234
61 + 31584173 = 31584234
167 + 31584067 = 31584234
191 + 31584043 = 31584234
251 + 31583983 = 31584234

Showing the first eight; more decompositions exist.
