Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624534, here are decompositions:

23 + 31624511 = 31624534
167 + 31624367 = 31624534
191 + 31624343 = 31624534
197 + 31624337 = 31624534
251 + 31624283 = 31624534
257 + 31624277 = 31624534
317 + 31624217 = 31624534
521 + 31624013 = 31624534

Showing the first eight; more decompositions exist.
