Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743844, here are decompositions:

7 + 8743837 = 8743844
37 + 8743807 = 8743844
73 + 8743771 = 8743844
97 + 8743747 = 8743844
127 + 8743717 = 8743844
163 + 8743681 = 8743844
211 + 8743633 = 8743844
223 + 8743621 = 8743844

Showing the first eight; more decompositions exist.
