Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528170, here are decompositions:

3 + 528167 = 528170
7 + 528163 = 528170
43 + 528127 = 528170
73 + 528097 = 528170
79 + 528091 = 528170
127 + 528043 = 528170
157 + 528013 = 528170
229 + 527941 = 528170

Showing the first eight; more decompositions exist.
