Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470872, here are decompositions:

5 + 470867 = 470872
41 + 470831 = 470872
53 + 470819 = 470872
89 + 470783 = 470872
251 + 470621 = 470872
263 + 470609 = 470872
293 + 470579 = 470872
359 + 470513 = 470872

Showing the first eight; more decompositions exist.
