Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497878, here are decompositions:

5 + 497873 = 497878
11 + 497867 = 497878
47 + 497831 = 497878
107 + 497771 = 497878
137 + 497741 = 497878
149 + 497729 = 497878
167 + 497711 = 497878
281 + 497597 = 497878

Showing the first eight; more decompositions exist.
