Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472580, here are decompositions:

7 + 472573 = 472580
19 + 472561 = 472580
37 + 472543 = 472580
103 + 472477 = 472580
181 + 472399 = 472580
211 + 472369 = 472580
271 + 472309 = 472580
307 + 472273 = 472580

Showing the first eight; more decompositions exist.
