Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624962, here are decompositions:

11 + 31624951 = 31624962
23 + 31624939 = 31624962
41 + 31624921 = 31624962
101 + 31624861 = 31624962
113 + 31624849 = 31624962
163 + 31624799 = 31624962
179 + 31624783 = 31624962
181 + 31624781 = 31624962

Showing the first eight; more decompositions exist.
