Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528186, here are decompositions:

19 + 528167 = 528186
23 + 528163 = 528186
59 + 528127 = 528186
79 + 528107 = 528186
89 + 528097 = 528186
173 + 528013 = 528186
193 + 527993 = 528186
199 + 527987 = 528186

Showing the first eight; more decompositions exist.
