Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538256, here are decompositions:

7 + 538249 = 538256
97 + 538159 = 538256
109 + 538147 = 538256
139 + 538117 = 538256
163 + 538093 = 538256
337 + 537919 = 538256
373 + 537883 = 538256
379 + 537877 = 538256

Showing the first eight; more decompositions exist.
