Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743988, here are decompositions:

7 + 8743981 = 8743988
109 + 8743879 = 8743988
151 + 8743837 = 8743988
181 + 8743807 = 8743988
241 + 8743747 = 8743988
271 + 8743717 = 8743988
277 + 8743711 = 8743988
307 + 8743681 = 8743988

Showing the first eight; more decompositions exist.
