Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513306, here are decompositions:

23 + 513283 = 513306
29 + 513277 = 513306
37 + 513269 = 513306
67 + 513239 = 513306
103 + 513203 = 513306
137 + 513169 = 513306
139 + 513167 = 513306
149 + 513157 = 513306

Showing the first eight; more decompositions exist.
