Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528754, here are decompositions:

47 + 528707 = 528754
131 + 528623 = 528754
227 + 528527 = 528754
263 + 528491 = 528754
353 + 528401 = 528754
491 + 528263 = 528754
557 + 528197 = 528754
563 + 528191 = 528754

Showing the first eight; more decompositions exist.
