Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516318, here are decompositions:

41 + 516277 = 516318
67 + 516251 = 516318
71 + 516247 = 516318
109 + 516209 = 516318
139 + 516179 = 516318
149 + 516169 = 516318
157 + 516161 = 516318
167 + 516151 = 516318

Showing the first eight; more decompositions exist.
