Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520986, here are decompositions:

5 + 520981 = 520986
17 + 520969 = 520986
19 + 520967 = 520986
23 + 520963 = 520986
29 + 520957 = 520986
43 + 520943 = 520986
73 + 520913 = 520986
97 + 520889 = 520986

Showing the first eight; more decompositions exist.
