Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707870, here are decompositions:

29 + 8707841 = 8707870
53 + 8707817 = 8707870
89 + 8707781 = 8707870
107 + 8707763 = 8707870
173 + 8707697 = 8707870
239 + 8707631 = 8707870
263 + 8707607 = 8707870
449 + 8707421 = 8707870

Showing the first eight; more decompositions exist.
