Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624998, here are decompositions:

19 + 31624979 = 31624998
47 + 31624951 = 31624998
59 + 31624939 = 31624998
71 + 31624927 = 31624998
137 + 31624861 = 31624998
149 + 31624849 = 31624998
191 + 31624807 = 31624998
199 + 31624799 = 31624998

Showing the first eight; more decompositions exist.
