Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475238, here are decompositions:

19 + 475219 = 475238
31 + 475207 = 475238
79 + 475159 = 475238
97 + 475141 = 475238
157 + 475081 = 475238
307 + 474931 = 475238
331 + 474907 = 475238
487 + 474751 = 475238

Showing the first eight; more decompositions exist.
