Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624314, here are decompositions:

31 + 31624283 = 31624314
37 + 31624277 = 31624314
97 + 31624217 = 31624314
167 + 31624147 = 31624314
173 + 31624141 = 31624314
311 + 31624003 = 31624314
313 + 31624001 = 31624314
331 + 31623983 = 31624314

Showing the first eight; more decompositions exist.
