Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481788, here are decompositions:

19 + 481769 = 481788
37 + 481751 = 481788
67 + 481721 = 481788
89 + 481699 = 481788
107 + 481681 = 481788
137 + 481651 = 481788
149 + 481639 = 481788
199 + 481589 = 481788

Showing the first eight; more decompositions exist.
