Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525822, here are decompositions:

5 + 525817 = 525822
13 + 525809 = 525822
41 + 525781 = 525822
53 + 525769 = 525822
83 + 525739 = 525822
103 + 525719 = 525822
109 + 525713 = 525822
113 + 525709 = 525822

Showing the first eight; more decompositions exist.
