Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624152, here are decompositions:

5 + 31624147 = 31624152
11 + 31624141 = 31624152
23 + 31624129 = 31624152
83 + 31624069 = 31624152
139 + 31624013 = 31624152
149 + 31624003 = 31624152
151 + 31624001 = 31624152
163 + 31623989 = 31624152

Showing the first eight; more decompositions exist.
