Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465228, here are decompositions:

17 + 465211 = 465228
19 + 465209 = 465228
41 + 465187 = 465228
59 + 465169 = 465228
61 + 465167 = 465228
67 + 465161 = 465228
109 + 465119 = 465228
139 + 465089 = 465228

Showing the first eight; more decompositions exist.
