Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520222, here are decompositions:

29 + 520193 = 520222
71 + 520151 = 520222
149 + 520073 = 520222
179 + 520043 = 520222
191 + 520031 = 520222
233 + 519989 = 520222
251 + 519971 = 520222
359 + 519863 = 520222

Showing the first eight; more decompositions exist.
