Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521952, here are decompositions:

23 + 521929 = 521952
29 + 521923 = 521952
71 + 521881 = 521952
73 + 521879 = 521952
83 + 521869 = 521952
139 + 521813 = 521952
163 + 521789 = 521952
199 + 521753 = 521952

Showing the first eight; more decompositions exist.
