Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043542, here are decompositions:

11 + 1043531 = 1043542
29 + 1043513 = 1043542
41 + 1043501 = 1043542
53 + 1043489 = 1043542
89 + 1043453 = 1043542
173 + 1043369 = 1043542
191 + 1043351 = 1043542
251 + 1043291 = 1043542

Showing the first eight; more decompositions exist.
