Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471918, here are decompositions:

11 + 471907 = 471918
17 + 471901 = 471918
47 + 471871 = 471918
71 + 471847 = 471918
101 + 471817 = 471918
127 + 471791 = 471918
137 + 471781 = 471918
149 + 471769 = 471918

Showing the first eight; more decompositions exist.
