Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518236, here are decompositions:

3 + 518233 = 518236
29 + 518207 = 518236
83 + 518153 = 518236
107 + 518129 = 518236
113 + 518123 = 518236
137 + 518099 = 518236
179 + 518057 = 518236
269 + 517967 = 518236

Showing the first eight; more decompositions exist.
