Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029542, here are decompositions:

43 + 1029499 = 1029542
61 + 1029481 = 1029542
109 + 1029433 = 1029542
139 + 1029403 = 1029542
181 + 1029361 = 1029542
193 + 1029349 = 1029542
211 + 1029331 = 1029542
433 + 1029109 = 1029542

Showing the first eight; more decompositions exist.
