Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538432, here are decompositions:

101 + 538331 = 538432
131 + 538301 = 538432
149 + 538283 = 538432
173 + 538259 = 538432
233 + 538199 = 538432
269 + 538163 = 538432
281 + 538151 = 538432
311 + 538121 = 538432

Showing the first eight; more decompositions exist.
