Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471690, here are decompositions:

7 + 471683 = 471690
13 + 471677 = 471690
17 + 471673 = 471690
19 + 471671 = 471690
31 + 471659 = 471690
41 + 471649 = 471690
71 + 471619 = 471690
73 + 471617 = 471690

Showing the first eight; more decompositions exist.
