Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518068, here are decompositions:

11 + 518057 = 518068
101 + 517967 = 518068
137 + 517931 = 518068
149 + 517919 = 518068
167 + 517901 = 518068
191 + 517877 = 518068
251 + 517817 = 518068
347 + 517721 = 518068

Showing the first eight; more decompositions exist.
