Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 461220, here are decompositions:

13 + 461207 = 461220
29 + 461191 = 461220
37 + 461183 = 461220
73 + 461147 = 461220
101 + 461119 = 461220
127 + 461093 = 461220
167 + 461053 = 461220
211 + 461009 = 461220

Showing the first eight; more decompositions exist.
