Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584806, here are decompositions:

37 + 31584769 = 31584806
103 + 31584703 = 31584806
109 + 31584697 = 31584806
139 + 31584667 = 31584806
193 + 31584613 = 31584806
199 + 31584607 = 31584806
229 + 31584577 = 31584806
283 + 31584523 = 31584806

Showing the first eight; more decompositions exist.
