Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478872, here are decompositions:

11 + 478861 = 478872
19 + 478853 = 478872
29 + 478843 = 478872
41 + 478831 = 478872
59 + 478813 = 478872
61 + 478811 = 478872
71 + 478801 = 478872
103 + 478769 = 478872

Showing the first eight; more decompositions exist.
