Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525910, here are decompositions:

17 + 525893 = 525910
23 + 525887 = 525910
41 + 525869 = 525910
71 + 525839 = 525910
101 + 525809 = 525910
137 + 525773 = 525910
179 + 525731 = 525910
191 + 525719 = 525910

Showing the first eight; more decompositions exist.
