Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520156, here are decompositions:

5 + 520151 = 520156
53 + 520103 = 520156
83 + 520073 = 520156
89 + 520067 = 520156
113 + 520043 = 520156
137 + 520019 = 520156
167 + 519989 = 520156
233 + 519923 = 520156

Showing the first eight; more decompositions exist.
