Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623852, here are decompositions:

31 + 31623821 = 31623852
131 + 31623721 = 31623852
149 + 31623703 = 31623852
151 + 31623701 = 31623852
181 + 31623671 = 31623852
229 + 31623623 = 31623852
263 + 31623589 = 31623852
331 + 31623521 = 31623852

Showing the first eight; more decompositions exist.
