Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478916, here are decompositions:

3 + 478913 = 478916
19 + 478897 = 478916
37 + 478879 = 478916
73 + 478843 = 478916
103 + 478813 = 478916
313 + 478603 = 478916
337 + 478579 = 478916
433 + 478483 = 478916

Showing the first eight; more decompositions exist.
