Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704986, here are decompositions:

5 + 8704981 = 8704986
7 + 8704979 = 8704986
13 + 8704973 = 8704986
19 + 8704967 = 8704986
83 + 8704903 = 8704986
89 + 8704897 = 8704986
97 + 8704889 = 8704986
149 + 8704837 = 8704986

Showing the first eight; more decompositions exist.
