Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515300, here are decompositions:

7 + 515293 = 515300
67 + 515233 = 515300
73 + 515227 = 515300
109 + 515191 = 515300
127 + 515173 = 515300
151 + 515149 = 515300
157 + 515143 = 515300
211 + 515089 = 515300

Showing the first eight; more decompositions exist.
