Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527218, here are decompositions:

11 + 527207 = 527218
59 + 527159 = 527218
89 + 527129 = 527218
137 + 527081 = 527218
149 + 527069 = 527218
281 + 526937 = 527218
347 + 526871 = 527218
359 + 526859 = 527218

Showing the first eight; more decompositions exist.
