Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471820, here are decompositions:

3 + 471817 = 471820
17 + 471803 = 471820
29 + 471791 = 471820
71 + 471749 = 471820
101 + 471719 = 471820
137 + 471683 = 471820
149 + 471671 = 471820
179 + 471641 = 471820

Showing the first eight; more decompositions exist.
