Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584232, here are decompositions:

41 + 31584191 = 31584232
59 + 31584173 = 31584232
89 + 31584143 = 31584232
131 + 31584101 = 31584232
233 + 31583999 = 31584232
311 + 31583921 = 31584232
401 + 31583831 = 31584232
461 + 31583771 = 31584232

Showing the first eight; more decompositions exist.
