Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624506, here are decompositions:

29 + 31624477 = 31624506
83 + 31624423 = 31624506
139 + 31624367 = 31624506
149 + 31624357 = 31624506
157 + 31624349 = 31624506
163 + 31624343 = 31624506
167 + 31624339 = 31624506
223 + 31624283 = 31624506

Showing the first eight; more decompositions exist.
