Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520212, here are decompositions:

19 + 520193 = 520212
61 + 520151 = 520212
83 + 520129 = 520212
89 + 520123 = 520212
101 + 520111 = 520212
109 + 520103 = 520212
139 + 520073 = 520212
149 + 520063 = 520212

Showing the first eight; more decompositions exist.
