Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584482, here are decompositions:

43 + 31584439 = 31584482
109 + 31584373 = 31584482
271 + 31584211 = 31584482
439 + 31584043 = 31584482
463 + 31584019 = 31584482
499 + 31583983 = 31584482
541 + 31583941 = 31584482
571 + 31583911 = 31584482

Showing the first eight; more decompositions exist.
