Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472858, here are decompositions:

11 + 472847 = 472858
41 + 472817 = 472858
59 + 472799 = 472858
107 + 472751 = 472858
137 + 472721 = 472858
149 + 472709 = 472858
167 + 472691 = 472858
227 + 472631 = 472858

Showing the first eight; more decompositions exist.
