Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536542, here are decompositions:

11 + 536531 = 536542
29 + 536513 = 536542
89 + 536453 = 536542
101 + 536441 = 536542
263 + 536279 = 536542
269 + 536273 = 536542
353 + 536189 = 536542
401 + 536141 = 536542

Showing the first eight; more decompositions exist.
