Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707880, here are decompositions:

3 + 8707877 = 8707880
7 + 8707873 = 8707880
19 + 8707861 = 8707880
37 + 8707843 = 8707880
43 + 8707837 = 8707880
127 + 8707753 = 8707880
193 + 8707687 = 8707880
211 + 8707669 = 8707880

Showing the first eight; more decompositions exist.
