Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478864, here are decompositions:

3 + 478861 = 478864
11 + 478853 = 478864
41 + 478823 = 478864
53 + 478811 = 478864
101 + 478763 = 478864
137 + 478727 = 478864
167 + 478697 = 478864
227 + 478637 = 478864

Showing the first eight; more decompositions exist.
