Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518288, here are decompositions:

79 + 518209 = 518288
97 + 518191 = 518288
109 + 518179 = 518288
151 + 518137 = 518288
157 + 518131 = 518288
229 + 518059 = 518288
241 + 518047 = 518288
271 + 518017 = 518288

Showing the first eight; more decompositions exist.
