Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047042, here are decompositions:

11 + 1047031 = 1047042
43 + 1046999 = 1047042
83 + 1046959 = 1047042
109 + 1046933 = 1047042
179 + 1046863 = 1047042
193 + 1046849 = 1047042
251 + 1046791 = 1047042
263 + 1046779 = 1047042

Showing the first eight; more decompositions exist.
