Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538266, here are decompositions:

7 + 538259 = 538266
17 + 538249 = 538266
19 + 538247 = 538266
67 + 538199 = 538266
103 + 538163 = 538266
107 + 538159 = 538266
109 + 538157 = 538266
139 + 538127 = 538266

Showing the first eight; more decompositions exist.
