Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471980, here are decompositions:

31 + 471949 = 471980
37 + 471943 = 471980
73 + 471907 = 471980
79 + 471901 = 471980
109 + 471871 = 471980
127 + 471853 = 471980
139 + 471841 = 471980
163 + 471817 = 471980

Showing the first eight; more decompositions exist.
