Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584936, here are decompositions:

29 + 31584907 = 31584936
67 + 31584869 = 31584936
83 + 31584853 = 31584936
107 + 31584829 = 31584936
113 + 31584823 = 31584936
127 + 31584809 = 31584936
139 + 31584797 = 31584936
167 + 31584769 = 31584936

Showing the first eight; more decompositions exist.
