Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572166, here are decompositions:

5 + 572161 = 572166
29 + 572137 = 572166
59 + 572107 = 572166
73 + 572093 = 572166
79 + 572087 = 572166
97 + 572069 = 572166
103 + 572063 = 572166
107 + 572059 = 572166

Showing the first eight; more decompositions exist.
