Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624572, here are decompositions:

13 + 31624559 = 31624572
61 + 31624511 = 31624572
149 + 31624423 = 31624572
223 + 31624349 = 31624572
229 + 31624343 = 31624572
233 + 31624339 = 31624572
241 + 31624331 = 31624572
251 + 31624321 = 31624572

Showing the first eight; more decompositions exist.
