Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743898, here are decompositions:

19 + 8743879 = 8743898
61 + 8743837 = 8743898
127 + 8743771 = 8743898
151 + 8743747 = 8743898
181 + 8743717 = 8743898
277 + 8743621 = 8743898
337 + 8743561 = 8743898
349 + 8743549 = 8743898

Showing the first eight; more decompositions exist.
