Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472572, here are decompositions:

11 + 472561 = 472572
13 + 472559 = 472572
29 + 472543 = 472572
31 + 472541 = 472572
103 + 472469 = 472572
151 + 472421 = 472572
173 + 472399 = 472572
179 + 472393 = 472572

Showing the first eight; more decompositions exist.
