Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624512, here are decompositions:

5 + 31624507 = 31624512
83 + 31624429 = 31624512
89 + 31624423 = 31624512
149 + 31624363 = 31624512
163 + 31624349 = 31624512
173 + 31624339 = 31624512
181 + 31624331 = 31624512
191 + 31624321 = 31624512

Showing the first eight; more decompositions exist.
