Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471540, here are decompositions:

7 + 471533 = 471540
19 + 471521 = 471540
31 + 471509 = 471540
37 + 471503 = 471540
53 + 471487 = 471540
59 + 471481 = 471540
73 + 471467 = 471540
89 + 471451 = 471540

Showing the first eight; more decompositions exist.
