Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528902, here are decompositions:

19 + 528883 = 528902
79 + 528823 = 528902
103 + 528799 = 528902
139 + 528763 = 528902
193 + 528709 = 528902
211 + 528691 = 528902
223 + 528679 = 528902
229 + 528673 = 528902

Showing the first eight; more decompositions exist.
