Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471218, here are decompositions:

31 + 471187 = 471218
79 + 471139 = 471218
127 + 471091 = 471218
157 + 471061 = 471218
211 + 471007 = 471218
271 + 470947 = 471218
277 + 470941 = 471218
331 + 470887 = 471218

Showing the first eight; more decompositions exist.
