Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472740, here are decompositions:

19 + 472721 = 472740
29 + 472711 = 472740
31 + 472709 = 472740
43 + 472697 = 472740
53 + 472687 = 472740
71 + 472669 = 472740
97 + 472643 = 472740
101 + 472639 = 472740

Showing the first eight; more decompositions exist.
