Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481998, here are decompositions:

59 + 481939 = 481998
89 + 481909 = 481998
131 + 481867 = 481998
137 + 481861 = 481998
149 + 481849 = 481998
151 + 481847 = 481998
191 + 481807 = 481998
197 + 481801 = 481998

Showing the first eight; more decompositions exist.
