Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518188, here are decompositions:

17 + 518171 = 518188
29 + 518159 = 518188
59 + 518129 = 518188
89 + 518099 = 518188
131 + 518057 = 518188
197 + 517991 = 518188
239 + 517949 = 518188
257 + 517931 = 518188

Showing the first eight; more decompositions exist.
