Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018788, here are decompositions:

11 + 1018777 = 1018788
19 + 1018769 = 1018788
59 + 1018729 = 1018788
79 + 1018709 = 1018788
109 + 1018679 = 1018788
137 + 1018651 = 1018788
139 + 1018649 = 1018788
167 + 1018621 = 1018788

Showing the first eight; more decompositions exist.
