Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472438, here are decompositions:

17 + 472421 = 472438
47 + 472391 = 472438
89 + 472349 = 472438
107 + 472331 = 472438
137 + 472301 = 472438
149 + 472289 = 472438
191 + 472247 = 472438
311 + 472127 = 472438

Showing the first eight; more decompositions exist.
