Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538526, here are decompositions:

3 + 538523 = 538526
7 + 538519 = 538526
13 + 538513 = 538526
103 + 538423 = 538526
127 + 538399 = 538526
193 + 538333 = 538526
223 + 538303 = 538526
229 + 538297 = 538526

Showing the first eight; more decompositions exist.
