Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478890, here are decompositions:

11 + 478879 = 478890
19 + 478871 = 478890
29 + 478861 = 478890
37 + 478853 = 478890
47 + 478843 = 478890
59 + 478831 = 478890
67 + 478823 = 478890
79 + 478811 = 478890

Showing the first eight; more decompositions exist.
