Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043042, here are decompositions:

19 + 1043023 = 1043042
31 + 1043011 = 1043042
139 + 1042903 = 1043042
181 + 1042861 = 1043042
193 + 1042849 = 1043042
223 + 1042819 = 1043042
283 + 1042759 = 1043042
349 + 1042693 = 1043042

Showing the first eight; more decompositions exist.
