Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472208, here are decompositions:

19 + 472189 = 472208
97 + 472111 = 472208
151 + 472057 = 472208
157 + 472051 = 472208
181 + 472027 = 472208
211 + 471997 = 472208
277 + 471931 = 472208
307 + 471901 = 472208

Showing the first eight; more decompositions exist.
