Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528782, here are decompositions:

3 + 528779 = 528782
19 + 528763 = 528782
73 + 528709 = 528782
103 + 528679 = 528782
109 + 528673 = 528782
151 + 528631 = 528782
223 + 528559 = 528782
271 + 528511 = 528782

Showing the first eight; more decompositions exist.
