Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584464, here are decompositions:

7 + 31584457 = 31584464
103 + 31584361 = 31584464
127 + 31584337 = 31584464
157 + 31584307 = 31584464
271 + 31584193 = 31584464
397 + 31584067 = 31584464
421 + 31584043 = 31584464
523 + 31583941 = 31584464

Showing the first eight; more decompositions exist.
