Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520998, here are decompositions:

17 + 520981 = 520998
29 + 520969 = 520998
31 + 520967 = 520998
41 + 520957 = 520998
109 + 520889 = 520998
131 + 520867 = 520998
157 + 520841 = 520998
211 + 520787 = 520998

Showing the first eight; more decompositions exist.
