Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518290, here are decompositions:

29 + 518261 = 518290
41 + 518249 = 518290
53 + 518237 = 518290
83 + 518207 = 518290
131 + 518159 = 518290
137 + 518153 = 518290
167 + 518123 = 518290
191 + 518099 = 518290

Showing the first eight; more decompositions exist.
