Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740870, here are decompositions:

3 + 8740867 = 8740870
11 + 8740859 = 8740870
29 + 8740841 = 8740870
71 + 8740799 = 8740870
107 + 8740763 = 8740870
113 + 8740757 = 8740870
191 + 8740679 = 8740870
227 + 8740643 = 8740870

Showing the first eight; more decompositions exist.
