Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471816, here are decompositions:

13 + 471803 = 471816
47 + 471769 = 471816
67 + 471749 = 471816
97 + 471719 = 471816
113 + 471703 = 471816
139 + 471677 = 471816
157 + 471659 = 471816
167 + 471649 = 471816

Showing the first eight; more decompositions exist.
