Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705020, here are decompositions:

11 + 8705009 = 8705020
41 + 8704979 = 8705020
47 + 8704973 = 8705020
53 + 8704967 = 8705020
83 + 8704937 = 8705020
131 + 8704889 = 8705020
167 + 8704853 = 8705020
263 + 8704757 = 8705020

Showing the first eight; more decompositions exist.
