Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743644, here are decompositions:

5 + 8743639 = 8743644
11 + 8743633 = 8743644
23 + 8743621 = 8743644
47 + 8743597 = 8743644
61 + 8743583 = 8743644
73 + 8743571 = 8743644
83 + 8743561 = 8743644
97 + 8743547 = 8743644

Showing the first eight; more decompositions exist.
