Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627880, here are decompositions:

13 + 8627867 = 8627880
29 + 8627851 = 8627880
47 + 8627833 = 8627880
67 + 8627813 = 8627880
71 + 8627809 = 8627880
73 + 8627807 = 8627880
103 + 8627777 = 8627880
139 + 8627741 = 8627880

Showing the first eight; more decompositions exist.
