Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478900, here are decompositions:

3 + 478897 = 478900
29 + 478871 = 478900
47 + 478853 = 478900
89 + 478811 = 478900
113 + 478787 = 478900
131 + 478769 = 478900
137 + 478763 = 478900
173 + 478727 = 478900

Showing the first eight; more decompositions exist.
