Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528774, here are decompositions:

11 + 528763 = 528774
67 + 528707 = 528774
83 + 528691 = 528774
101 + 528673 = 528774
107 + 528667 = 528774
151 + 528623 = 528774
163 + 528611 = 528774
263 + 528511 = 528774

Showing the first eight; more decompositions exist.
