Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584954, here are decompositions:

7 + 31584947 = 31584954
47 + 31584907 = 31584954
53 + 31584901 = 31584954
67 + 31584887 = 31584954
73 + 31584881 = 31584954
101 + 31584853 = 31584954
131 + 31584823 = 31584954
157 + 31584797 = 31584954

Showing the first eight; more decompositions exist.
