Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528142, here are decompositions:

5 + 528137 = 528142
11 + 528131 = 528142
89 + 528053 = 528142
101 + 528041 = 528142
149 + 527993 = 528142
233 + 527909 = 528142
353 + 527789 = 528142
389 + 527753 = 528142

Showing the first eight; more decompositions exist.
