Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518206, here are decompositions:

47 + 518159 = 518206
53 + 518153 = 518206
83 + 518123 = 518206
107 + 518099 = 518206
149 + 518057 = 518206
239 + 517967 = 518206
257 + 517949 = 518206
383 + 517823 = 518206

Showing the first eight; more decompositions exist.
