Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743746, here are decompositions:

13 + 8743733 = 8743746
29 + 8743717 = 8743746
73 + 8743673 = 8743746
107 + 8743639 = 8743746
113 + 8743633 = 8743746
149 + 8743597 = 8743746
157 + 8743589 = 8743746
163 + 8743583 = 8743746

Showing the first eight; more decompositions exist.
