Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624822, here are decompositions:

23 + 31624799 = 31624822
41 + 31624781 = 31624822
59 + 31624763 = 31624822
83 + 31624739 = 31624822
149 + 31624673 = 31624822
179 + 31624643 = 31624822
191 + 31624631 = 31624822
263 + 31624559 = 31624822

Showing the first eight; more decompositions exist.
