Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520992, here are decompositions:

11 + 520981 = 520992
23 + 520969 = 520992
29 + 520963 = 520992
71 + 520921 = 520992
79 + 520913 = 520992
103 + 520889 = 520992
139 + 520853 = 520992
151 + 520841 = 520992

Showing the first eight; more decompositions exist.
