Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755880, here are decompositions:

31 + 8755849 = 8755880
61 + 8755819 = 8755880
139 + 8755741 = 8755880
151 + 8755729 = 8755880
157 + 8755723 = 8755880
181 + 8755699 = 8755880
241 + 8755639 = 8755880
277 + 8755603 = 8755880

Showing the first eight; more decompositions exist.
