Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624848, here are decompositions:

11 + 31624837 = 31624848
19 + 31624829 = 31624848
41 + 31624807 = 31624848
67 + 31624781 = 31624848
107 + 31624741 = 31624848
109 + 31624739 = 31624848
131 + 31624717 = 31624848
149 + 31624699 = 31624848

Showing the first eight; more decompositions exist.
