Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479940, here are decompositions:

31 + 479909 = 479940
37 + 479903 = 479940
59 + 479881 = 479940
61 + 479879 = 479940
79 + 479861 = 479940
101 + 479839 = 479940
107 + 479833 = 479940
127 + 479813 = 479940

Showing the first eight; more decompositions exist.
