Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538426, here are decompositions:

3 + 538423 = 538426
29 + 538397 = 538426
59 + 538367 = 538426
167 + 538259 = 538426
179 + 538247 = 538426
227 + 538199 = 538426
263 + 538163 = 538426
269 + 538157 = 538426

Showing the first eight; more decompositions exist.
