Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624852, here are decompositions:

3 + 31624849 = 31624852
23 + 31624829 = 31624852
53 + 31624799 = 31624852
71 + 31624781 = 31624852
89 + 31624763 = 31624852
113 + 31624739 = 31624852
179 + 31624673 = 31624852
191 + 31624661 = 31624852

Showing the first eight; more decompositions exist.
