Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584994, here are decompositions:

41 + 31584953 = 31584994
47 + 31584947 = 31584994
107 + 31584887 = 31584994
113 + 31584881 = 31584994
197 + 31584797 = 31584994
281 + 31584713 = 31584994
443 + 31584551 = 31584994
563 + 31584431 = 31584994

Showing the first eight; more decompositions exist.
