Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528884, here are decompositions:

3 + 528881 = 528884
7 + 528877 = 528884
61 + 528823 = 528884
73 + 528811 = 528884
193 + 528691 = 528884
211 + 528673 = 528884
373 + 528511 = 528884
397 + 528487 = 528884

Showing the first eight; more decompositions exist.
