Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479730, here are decompositions:

29 + 479701 = 479730
101 + 479629 = 479730
107 + 479623 = 479730
131 + 479599 = 479730
137 + 479593 = 479730
149 + 479581 = 479730
197 + 479533 = 479730
233 + 479497 = 479730

Showing the first eight; more decompositions exist.
