Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525912, here are decompositions:

19 + 525893 = 525912
41 + 525871 = 525912
43 + 525869 = 525912
73 + 525839 = 525912
103 + 525809 = 525912
131 + 525781 = 525912
139 + 525773 = 525912
173 + 525739 = 525912

Showing the first eight; more decompositions exist.
