Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478854, here are decompositions:

11 + 478843 = 478854
23 + 478831 = 478854
31 + 478823 = 478854
41 + 478813 = 478854
43 + 478811 = 478854
53 + 478801 = 478854
67 + 478787 = 478854
107 + 478747 = 478854

Showing the first eight; more decompositions exist.
