Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525780, here are decompositions:

7 + 525773 = 525780
11 + 525769 = 525780
41 + 525739 = 525780
53 + 525727 = 525780
61 + 525719 = 525780
67 + 525713 = 525780
71 + 525709 = 525780
83 + 525697 = 525780

Showing the first eight; more decompositions exist.
