Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472180, here are decompositions:

17 + 472163 = 472180
29 + 472151 = 472180
41 + 472139 = 472180
47 + 472133 = 472180
53 + 472127 = 472180
113 + 472067 = 472180
251 + 471929 = 472180
257 + 471923 = 472180

Showing the first eight; more decompositions exist.
