Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471538, here are decompositions:

5 + 471533 = 471538
17 + 471521 = 471538
29 + 471509 = 471538
71 + 471467 = 471538
131 + 471407 = 471538
149 + 471389 = 471538
239 + 471299 = 471538
257 + 471281 = 471538

Showing the first eight; more decompositions exist.
