Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624932, here are decompositions:

5 + 31624927 = 31624932
11 + 31624921 = 31624932
71 + 31624861 = 31624932
83 + 31624849 = 31624932
103 + 31624829 = 31624932
149 + 31624783 = 31624932
151 + 31624781 = 31624932
179 + 31624753 = 31624932

Showing the first eight; more decompositions exist.
