Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471938, here are decompositions:

7 + 471931 = 471938
31 + 471907 = 471938
37 + 471901 = 471938
67 + 471871 = 471938
97 + 471841 = 471938
157 + 471781 = 471938
241 + 471697 = 471938
331 + 471607 = 471938

Showing the first eight; more decompositions exist.
