Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584274, here are decompositions:

11 + 31584263 = 31584274
41 + 31584233 = 31584274
83 + 31584191 = 31584274
101 + 31584173 = 31584274
131 + 31584143 = 31584274
173 + 31584101 = 31584274
353 + 31583921 = 31584274
443 + 31583831 = 31584274

Showing the first eight; more decompositions exist.
