Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478884, here are decompositions:

5 + 478879 = 478884
13 + 478871 = 478884
23 + 478861 = 478884
31 + 478853 = 478884
41 + 478843 = 478884
53 + 478831 = 478884
61 + 478823 = 478884
71 + 478813 = 478884

Showing the first eight; more decompositions exist.
