Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465220, here are decompositions:

11 + 465209 = 465220
47 + 465173 = 465220
53 + 465167 = 465220
59 + 465161 = 465220
101 + 465119 = 465220
113 + 465107 = 465220
131 + 465089 = 465220
149 + 465071 = 465220

Showing the first eight; more decompositions exist.
