Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740880, here are decompositions:

13 + 8740867 = 8740880
73 + 8740807 = 8740880
97 + 8740783 = 8740880
199 + 8740681 = 8740880
223 + 8740657 = 8740880
277 + 8740603 = 8740880
349 + 8740531 = 8740880
433 + 8740447 = 8740880

Showing the first eight; more decompositions exist.
