Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528174, here are decompositions:

7 + 528167 = 528174
11 + 528163 = 528174
37 + 528137 = 528174
43 + 528131 = 528174
47 + 528127 = 528174
67 + 528107 = 528174
83 + 528091 = 528174
131 + 528043 = 528174

Showing the first eight; more decompositions exist.
