Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584932, here are decompositions:

31 + 31584901 = 31584932
79 + 31584853 = 31584932
103 + 31584829 = 31584932
109 + 31584823 = 31584932
163 + 31584769 = 31584932
229 + 31584703 = 31584932
331 + 31584601 = 31584932
373 + 31584559 = 31584932

Showing the first eight; more decompositions exist.
