Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584462, here are decompositions:

5 + 31584457 = 31584462
23 + 31584439 = 31584462
31 + 31584431 = 31584462
61 + 31584401 = 31584462
73 + 31584389 = 31584462
79 + 31584383 = 31584462
89 + 31584373 = 31584462
101 + 31584361 = 31584462

Showing the first eight; more decompositions exist.
