Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481018, here are decompositions:

17 + 481001 = 481018
29 + 480989 = 481018
59 + 480959 = 481018
89 + 480929 = 481018
107 + 480911 = 481018
137 + 480881 = 481018
179 + 480839 = 481018
191 + 480827 = 481018

Showing the first eight; more decompositions exist.
