Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739898, here are decompositions:

29 + 8739869 = 8739898
47 + 8739851 = 8739898
71 + 8739827 = 8739898
131 + 8739767 = 8739898
149 + 8739749 = 8739898
227 + 8739671 = 8739898
281 + 8739617 = 8739898
467 + 8739431 = 8739898

Showing the first eight; more decompositions exist.
