Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584950, here are decompositions:

3 + 31584947 = 31584950
43 + 31584907 = 31584950
97 + 31584853 = 31584950
127 + 31584823 = 31584950
181 + 31584769 = 31584950
193 + 31584757 = 31584950
283 + 31584667 = 31584950
337 + 31584613 = 31584950

Showing the first eight; more decompositions exist.
