Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739966, here are decompositions:

5 + 8739961 = 8739966
13 + 8739953 = 8739966
29 + 8739937 = 8739966
47 + 8739919 = 8739966
83 + 8739883 = 8739966
89 + 8739877 = 8739966
97 + 8739869 = 8739966
139 + 8739827 = 8739966

Showing the first eight; more decompositions exist.
