Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528194, here are decompositions:

3 + 528191 = 528194
31 + 528163 = 528194
67 + 528127 = 528194
97 + 528097 = 528194
103 + 528091 = 528194
151 + 528043 = 528194
181 + 528013 = 528194
193 + 528001 = 528194

Showing the first eight; more decompositions exist.
