Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584452, here are decompositions:

13 + 31584439 = 31584452
79 + 31584373 = 31584452
241 + 31584211 = 31584452
313 + 31584139 = 31584452
409 + 31584043 = 31584452
433 + 31584019 = 31584452
463 + 31583989 = 31584452
541 + 31583911 = 31584452

Showing the first eight; more decompositions exist.
