Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520090, here are decompositions:

17 + 520073 = 520090
23 + 520067 = 520090
47 + 520043 = 520090
59 + 520031 = 520090
71 + 520019 = 520090
101 + 519989 = 520090
167 + 519923 = 520090
173 + 519917 = 520090

Showing the first eight; more decompositions exist.
