Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532538, here are decompositions:

7 + 532531 = 532538
37 + 532501 = 532538
211 + 532327 = 532538
271 + 532267 = 532538
277 + 532261 = 532538
379 + 532159 = 532538
397 + 532141 = 532538
439 + 532099 = 532538

Showing the first eight; more decompositions exist.
