Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470940, here are decompositions:

7 + 470933 = 470940
13 + 470927 = 470940
37 + 470903 = 470940
53 + 470887 = 470940
59 + 470881 = 470940
73 + 470867 = 470940
103 + 470837 = 470940
109 + 470831 = 470940

Showing the first eight; more decompositions exist.
