Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 480690, here are decompositions:

29 + 480661 = 480690
43 + 480647 = 480690
103 + 480587 = 480690
107 + 480583 = 480690
127 + 480563 = 480690
137 + 480553 = 480690
149 + 480541 = 480690
157 + 480533 = 480690

Showing the first eight; more decompositions exist.
