Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471990, here are decompositions:

31 + 471959 = 471990
41 + 471949 = 471990
47 + 471943 = 471990
59 + 471931 = 471990
61 + 471929 = 471990
67 + 471923 = 471990
83 + 471907 = 471990
89 + 471901 = 471990

Showing the first eight; more decompositions exist.
