Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477218, here are decompositions:

127 + 477091 = 477218
199 + 477019 = 477218
229 + 476989 = 477218
241 + 476977 = 477218
307 + 476911 = 477218
331 + 476887 = 477218
349 + 476869 = 477218
367 + 476851 = 477218

Showing the first eight; more decompositions exist.
