Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584246, here are decompositions:

13 + 31584233 = 31584246
53 + 31584193 = 31584246
73 + 31584173 = 31584246
103 + 31584143 = 31584246
107 + 31584139 = 31584246
179 + 31584067 = 31584246
227 + 31584019 = 31584246
257 + 31583989 = 31584246

Showing the first eight; more decompositions exist.
