Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557166, here are decompositions:

7 + 557159 = 557166
13 + 557153 = 557166
73 + 557093 = 557166
79 + 557087 = 557166
97 + 557069 = 557166
107 + 557059 = 557166
109 + 557057 = 557166
139 + 557027 = 557166

Showing the first eight; more decompositions exist.
