Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472838, here are decompositions:

7 + 472831 = 472838
97 + 472741 = 472838
127 + 472711 = 472838
151 + 472687 = 472838
199 + 472639 = 472838
241 + 472597 = 472838
277 + 472561 = 472838
439 + 472399 = 472838

Showing the first eight; more decompositions exist.
