Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528130, here are decompositions:

3 + 528127 = 528130
23 + 528107 = 528130
89 + 528041 = 528130
137 + 527993 = 528130
149 + 527981 = 528130
233 + 527897 = 528130
311 + 527819 = 528130
389 + 527741 = 528130

Showing the first eight; more decompositions exist.
