Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528862, here are decompositions:

29 + 528833 = 528862
41 + 528821 = 528862
71 + 528791 = 528862
83 + 528779 = 528862
233 + 528629 = 528862
239 + 528623 = 528862
251 + 528611 = 528862
353 + 528509 = 528862

Showing the first eight; more decompositions exist.
