Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 473218, here are decompositions:

17 + 473201 = 473218
59 + 473159 = 473218
71 + 473147 = 473218
101 + 473117 = 473218
191 + 473027 = 473218
197 + 473021 = 473218
281 + 472937 = 473218
311 + 472907 = 473218

Showing the first eight; more decompositions exist.
