Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011842, here are decompositions:

43 + 1011799 = 1011842
79 + 1011763 = 1011842
109 + 1011733 = 1011842
193 + 1011649 = 1011842
211 + 1011631 = 1011842
241 + 1011601 = 1011842
283 + 1011559 = 1011842
499 + 1011343 = 1011842

Showing the first eight; more decompositions exist.
