Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472900, here are decompositions:

17 + 472883 = 472900
41 + 472859 = 472900
53 + 472847 = 472900
83 + 472817 = 472900
101 + 472799 = 472900
107 + 472793 = 472900
137 + 472763 = 472900
149 + 472751 = 472900

Showing the first eight; more decompositions exist.
