Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624198, here are decompositions:

71 + 31624127 = 31624198
197 + 31624001 = 31624198
227 + 31623971 = 31624198
239 + 31623959 = 31624198
251 + 31623947 = 31624198
269 + 31623929 = 31624198
311 + 31623887 = 31624198
401 + 31623797 = 31624198

Showing the first eight; more decompositions exist.
