Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 547218, here are decompositions:

47 + 547171 = 547218
79 + 547139 = 547218
97 + 547121 = 547218
131 + 547087 = 547218
157 + 547061 = 547218
181 + 547037 = 547218
197 + 547021 = 547218
211 + 547007 = 547218

Showing the first eight; more decompositions exist.
