Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471438, here are decompositions:

31 + 471407 = 471438
47 + 471391 = 471438
137 + 471301 = 471438
139 + 471299 = 471438
157 + 471281 = 471438
179 + 471259 = 471438
197 + 471241 = 471438
229 + 471209 = 471438

Showing the first eight; more decompositions exist.
