Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743986, here are decompositions:

5 + 8743981 = 8743986
23 + 8743963 = 8743986
67 + 8743919 = 8743986
73 + 8743913 = 8743986
103 + 8743883 = 8743986
107 + 8743879 = 8743986
149 + 8743837 = 8743986
179 + 8743807 = 8743986

Showing the first eight; more decompositions exist.
