Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584174, here are decompositions:

31 + 31584143 = 31584174
73 + 31584101 = 31584174
107 + 31584067 = 31584174
131 + 31584043 = 31584174
191 + 31583983 = 31584174
233 + 31583941 = 31584174
263 + 31583911 = 31584174
277 + 31583897 = 31584174

Showing the first eight; more decompositions exist.
