Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584214, here are decompositions:

3 + 31584211 = 31584214
17 + 31584197 = 31584214
23 + 31584191 = 31584214
41 + 31584173 = 31584214
71 + 31584143 = 31584214
113 + 31584101 = 31584214
293 + 31583921 = 31584214
317 + 31583897 = 31584214

Showing the first eight; more decompositions exist.
