Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584926, here are decompositions:

19 + 31584907 = 31584926
73 + 31584853 = 31584926
97 + 31584829 = 31584926
103 + 31584823 = 31584926
157 + 31584769 = 31584926
223 + 31584703 = 31584926
229 + 31584697 = 31584926
313 + 31584613 = 31584926

Showing the first eight; more decompositions exist.
