Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478920, here are decompositions:

7 + 478913 = 478920
19 + 478901 = 478920
23 + 478897 = 478920
41 + 478879 = 478920
59 + 478861 = 478920
67 + 478853 = 478920
89 + 478831 = 478920
97 + 478823 = 478920

Showing the first eight; more decompositions exist.
