Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528890, here are decompositions:

7 + 528883 = 528890
13 + 528877 = 528890
67 + 528823 = 528890
79 + 528811 = 528890
127 + 528763 = 528890
181 + 528709 = 528890
199 + 528691 = 528890
211 + 528679 = 528890

Showing the first eight; more decompositions exist.
