Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006542, here are decompositions:

11 + 1006531 = 1006542
29 + 1006513 = 1006542
71 + 1006471 = 1006542
73 + 1006469 = 1006542
79 + 1006463 = 1006542
101 + 1006441 = 1006542
109 + 1006433 = 1006542
149 + 1006393 = 1006542

Showing the first eight; more decompositions exist.
