Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516018, here are decompositions:

67 + 515951 = 516018
89 + 515929 = 516018
101 + 515917 = 516018
131 + 515887 = 516018
157 + 515861 = 516018
179 + 515839 = 516018
241 + 515777 = 516018
257 + 515761 = 516018

Showing the first eight; more decompositions exist.
