Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528854, here are decompositions:

31 + 528823 = 528854
43 + 528811 = 528854
163 + 528691 = 528854
181 + 528673 = 528854
223 + 528631 = 528854
367 + 528487 = 528854
421 + 528433 = 528854
463 + 528391 = 528854

Showing the first eight; more decompositions exist.
