Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 461218, here are decompositions:

11 + 461207 = 461218
47 + 461171 = 461218
71 + 461147 = 461218
167 + 461051 = 461218
227 + 460991 = 461218
239 + 460979 = 461218
269 + 460949 = 461218
281 + 460937 = 461218

Showing the first eight; more decompositions exist.
