Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481938, here are decompositions:

29 + 481909 = 481938
59 + 481879 = 481938
71 + 481867 = 481938
89 + 481849 = 481938
101 + 481837 = 481938
131 + 481807 = 481938
137 + 481801 = 481938
151 + 481787 = 481938

Showing the first eight; more decompositions exist.
