Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472238, here are decompositions:

79 + 472159 = 472238
127 + 472111 = 472238
181 + 472057 = 472238
211 + 472027 = 472238
241 + 471997 = 472238
307 + 471931 = 472238
331 + 471907 = 472238
337 + 471901 = 472238

Showing the first eight; more decompositions exist.
