Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472280, here are decompositions:

7 + 472273 = 472280
19 + 472261 = 472280
31 + 472249 = 472280
157 + 472123 = 472280
223 + 472057 = 472280
229 + 472051 = 472280
283 + 471997 = 472280
331 + 471949 = 472280

Showing the first eight; more decompositions exist.
