Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 462978, here are decompositions:

31 + 462947 = 462978
41 + 462937 = 462978
67 + 462911 = 462978
79 + 462899 = 462978
97 + 462881 = 462978
107 + 462871 = 462978
127 + 462851 = 462978
137 + 462841 = 462978

Showing the first eight; more decompositions exist.
