Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471810, here are decompositions:

7 + 471803 = 471810
19 + 471791 = 471810
29 + 471781 = 471810
41 + 471769 = 471810
61 + 471749 = 471810
89 + 471721 = 471810
107 + 471703 = 471810
113 + 471697 = 471810

Showing the first eight; more decompositions exist.
