Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624306, here are decompositions:

23 + 31624283 = 31624306
29 + 31624277 = 31624306
89 + 31624217 = 31624306
179 + 31624127 = 31624306
293 + 31624013 = 31624306
317 + 31623989 = 31624306
347 + 31623959 = 31624306
353 + 31623953 = 31624306

Showing the first eight; more decompositions exist.
