Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748840, here are decompositions:

13 + 8748827 = 8748840
19 + 8748821 = 8748840
29 + 8748811 = 8748840
53 + 8748787 = 8748840
73 + 8748767 = 8748840
97 + 8748743 = 8748840
101 + 8748739 = 8748840
109 + 8748731 = 8748840

Showing the first eight; more decompositions exist.
