Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513258, here are decompositions:

19 + 513239 = 513258
89 + 513169 = 513258
101 + 513157 = 513258
127 + 513131 = 513258
149 + 513109 = 513258
157 + 513101 = 513258
191 + 513067 = 513258
199 + 513059 = 513258

Showing the first eight; more decompositions exist.
