Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624974, here are decompositions:

23 + 31624951 = 31624974
47 + 31624927 = 31624974
53 + 31624921 = 31624974
67 + 31624907 = 31624974
113 + 31624861 = 31624974
137 + 31624837 = 31624974
167 + 31624807 = 31624974
191 + 31624783 = 31624974

Showing the first eight; more decompositions exist.
