Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528124, here are decompositions:

17 + 528107 = 528124
71 + 528053 = 528124
83 + 528041 = 528124
131 + 527993 = 528124
137 + 527987 = 528124
227 + 527897 = 528124
281 + 527843 = 528124
383 + 527741 = 528124

Showing the first eight; more decompositions exist.
