Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705080, here are decompositions:

3 + 8705077 = 8705080
11 + 8705069 = 8705080
23 + 8705057 = 8705080
29 + 8705051 = 8705080
47 + 8705033 = 8705080
71 + 8705009 = 8705080
101 + 8704979 = 8705080
107 + 8704973 = 8705080

Showing the first eight; more decompositions exist.
