Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624344, here are decompositions:

5 + 31624339 = 31624344
7 + 31624337 = 31624344
13 + 31624331 = 31624344
23 + 31624321 = 31624344
61 + 31624283 = 31624344
67 + 31624277 = 31624344
127 + 31624217 = 31624344
197 + 31624147 = 31624344

Showing the first eight; more decompositions exist.
