Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538420, here are decompositions:

23 + 538397 = 538420
53 + 538367 = 538420
89 + 538331 = 538420
137 + 538283 = 538420
173 + 538247 = 538420
257 + 538163 = 538420
263 + 538157 = 538420
269 + 538151 = 538420

Showing the first eight; more decompositions exist.
