Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739874, here are decompositions:

5 + 8739869 = 8739874
23 + 8739851 = 8739874
47 + 8739827 = 8739874
53 + 8739821 = 8739874
71 + 8739803 = 8739874
107 + 8739767 = 8739874
251 + 8739623 = 8739874
257 + 8739617 = 8739874

Showing the first eight; more decompositions exist.
