Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472784, here are decompositions:

43 + 472741 = 472784
73 + 472711 = 472784
97 + 472687 = 472784
211 + 472573 = 472784
223 + 472561 = 472784
241 + 472543 = 472784
307 + 472477 = 472784
373 + 472411 = 472784

Showing the first eight; more decompositions exist.
