Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584876, here are decompositions:

7 + 31584869 = 31584876
23 + 31584853 = 31584876
47 + 31584829 = 31584876
53 + 31584823 = 31584876
67 + 31584809 = 31584876
79 + 31584797 = 31584876
107 + 31584769 = 31584876
163 + 31584713 = 31584876

Showing the first eight; more decompositions exist.
