Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042788, here are decompositions:

7 + 1042781 = 1042788
29 + 1042759 = 1042788
79 + 1042709 = 1042788
101 + 1042687 = 1042788
107 + 1042681 = 1042788
157 + 1042631 = 1042788
179 + 1042609 = 1042788
181 + 1042607 = 1042788

Showing the first eight; more decompositions exist.
