Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478940, here are decompositions:

3 + 478937 = 478940
13 + 478927 = 478940
43 + 478897 = 478940
61 + 478879 = 478940
79 + 478861 = 478940
97 + 478843 = 478940
109 + 478831 = 478940
127 + 478813 = 478940

Showing the first eight; more decompositions exist.
