Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478946, here are decompositions:

3 + 478943 = 478946
19 + 478927 = 478946
67 + 478879 = 478946
103 + 478843 = 478946
199 + 478747 = 478946
367 + 478579 = 478946
373 + 478573 = 478946
463 + 478483 = 478946

Showing the first eight; more decompositions exist.
