Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518260, here are decompositions:

11 + 518249 = 518260
23 + 518237 = 518260
53 + 518207 = 518260
89 + 518171 = 518260
101 + 518159 = 518260
107 + 518153 = 518260
131 + 518129 = 518260
137 + 518123 = 518260

Showing the first eight; more decompositions exist.
