Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624884, here are decompositions:

23 + 31624861 = 31624884
47 + 31624837 = 31624884
101 + 31624783 = 31624884
103 + 31624781 = 31624884
131 + 31624753 = 31624884
167 + 31624717 = 31624884
211 + 31624673 = 31624884
223 + 31624661 = 31624884

Showing the first eight; more decompositions exist.
