Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518194, here are decompositions:

3 + 518191 = 518194
23 + 518171 = 518194
41 + 518153 = 518194
71 + 518123 = 518194
137 + 518057 = 518194
227 + 517967 = 518194
263 + 517931 = 518194
293 + 517901 = 518194

Showing the first eight; more decompositions exist.
