Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739886, here are decompositions:

3 + 8739883 = 8739886
17 + 8739869 = 8739886
59 + 8739827 = 8739886
83 + 8739803 = 8739886
137 + 8739749 = 8739886
173 + 8739713 = 8739886
263 + 8739623 = 8739886
269 + 8739617 = 8739886

Showing the first eight; more decompositions exist.
