Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477990, here are decompositions:

13 + 477977 = 477990
17 + 477973 = 477990
43 + 477947 = 477990
109 + 477881 = 477990
127 + 477863 = 477990
151 + 477839 = 477990
167 + 477823 = 477990
179 + 477811 = 477990

Showing the first eight; more decompositions exist.
