Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525906, here are decompositions:

13 + 525893 = 525906
19 + 525887 = 525906
37 + 525869 = 525906
67 + 525839 = 525906
89 + 525817 = 525906
97 + 525809 = 525906
137 + 525769 = 525906
167 + 525739 = 525906

Showing the first eight; more decompositions exist.
