Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584892, here are decompositions:

5 + 31584887 = 31584892
11 + 31584881 = 31584892
23 + 31584869 = 31584892
83 + 31584809 = 31584892
179 + 31584713 = 31584892
239 + 31584653 = 31584892
461 + 31584431 = 31584892
491 + 31584401 = 31584892

Showing the first eight; more decompositions exist.
