Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525858, here are decompositions:

19 + 525839 = 525858
41 + 525817 = 525858
89 + 525769 = 525858
127 + 525731 = 525858
131 + 525727 = 525858
139 + 525719 = 525858
149 + 525709 = 525858
181 + 525677 = 525858

Showing the first eight; more decompositions exist.
