Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481940, here are decompositions:

31 + 481909 = 481940
61 + 481879 = 481940
73 + 481867 = 481940
79 + 481861 = 481940
97 + 481843 = 481940
103 + 481837 = 481940
127 + 481813 = 481940
139 + 481801 = 481940

Showing the first eight; more decompositions exist.
