Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748880, here are decompositions:

3 + 8748877 = 8748880
53 + 8748827 = 8748880
59 + 8748821 = 8748880
113 + 8748767 = 8748880
137 + 8748743 = 8748880
149 + 8748731 = 8748880
167 + 8748713 = 8748880
227 + 8748653 = 8748880

Showing the first eight; more decompositions exist.
