Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525786, here are decompositions:

5 + 525781 = 525786
13 + 525773 = 525786
17 + 525769 = 525786
47 + 525739 = 525786
59 + 525727 = 525786
67 + 525719 = 525786
73 + 525713 = 525786
89 + 525697 = 525786

Showing the first eight; more decompositions exist.
