Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584746, here are decompositions:

43 + 31584703 = 31584746
79 + 31584667 = 31584746
139 + 31584607 = 31584746
199 + 31584547 = 31584746
223 + 31584523 = 31584746
307 + 31584439 = 31584746
373 + 31584373 = 31584746
409 + 31584337 = 31584746

Showing the first eight; more decompositions exist.
