Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528712, here are decompositions:

3 + 528709 = 528712
5 + 528707 = 528712
53 + 528659 = 528712
83 + 528629 = 528712
89 + 528623 = 528712
101 + 528611 = 528712
293 + 528419 = 528712
311 + 528401 = 528712

Showing the first eight; more decompositions exist.
