Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525972, here are decompositions:

11 + 525961 = 525972
19 + 525953 = 525972
23 + 525949 = 525972
59 + 525913 = 525972
79 + 525893 = 525972
101 + 525871 = 525972
103 + 525869 = 525972
163 + 525809 = 525972

Showing the first eight; more decompositions exist.
