Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624522, here are decompositions:

11 + 31624511 = 31624522
173 + 31624349 = 31624522
179 + 31624343 = 31624522
191 + 31624331 = 31624522
239 + 31624283 = 31624522
509 + 31624013 = 31624522
521 + 31624001 = 31624522
563 + 31623959 = 31624522

Showing the first eight; more decompositions exist.
