Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624150, here are decompositions:

3 + 31624147 = 31624150
23 + 31624127 = 31624150
137 + 31624013 = 31624150
149 + 31624001 = 31624150
167 + 31623983 = 31624150
179 + 31623971 = 31624150
191 + 31623959 = 31624150
197 + 31623953 = 31624150

Showing the first eight; more decompositions exist.
