Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556164, here are decompositions:

5 + 556159 = 556164
41 + 556123 = 556164
61 + 556103 = 556164
71 + 556093 = 556164
97 + 556067 = 556164
113 + 556051 = 556164
127 + 556037 = 556164
137 + 556027 = 556164

Showing the first eight; more decompositions exist.
