Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486990, here are decompositions:

13 + 486977 = 486990
19 + 486971 = 486990
41 + 486949 = 486990
43 + 486947 = 486990
47 + 486943 = 486990
61 + 486929 = 486990
67 + 486923 = 486990
83 + 486907 = 486990

Showing the first eight; more decompositions exist.
