Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538532, here are decompositions:

3 + 538529 = 538532
13 + 538519 = 538532
19 + 538513 = 538532
61 + 538471 = 538532
109 + 538423 = 538532
199 + 538333 = 538532
223 + 538309 = 538532
229 + 538303 = 538532

Showing the first eight; more decompositions exist.
