Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525900, here are decompositions:

7 + 525893 = 525900
13 + 525887 = 525900
29 + 525871 = 525900
31 + 525869 = 525900
61 + 525839 = 525900
83 + 525817 = 525900
127 + 525773 = 525900
131 + 525769 = 525900

Showing the first eight; more decompositions exist.
