Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743938, here are decompositions:

19 + 8743919 = 8743938
37 + 8743901 = 8743938
59 + 8743879 = 8743938
101 + 8743837 = 8743938
131 + 8743807 = 8743938
167 + 8743771 = 8743938
191 + 8743747 = 8743938
227 + 8743711 = 8743938

Showing the first eight; more decompositions exist.
