Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733840, here are decompositions:

7 + 8733833 = 8733840
13 + 8733827 = 8733840
19 + 8733821 = 8733840
29 + 8733811 = 8733840
97 + 8733743 = 8733840
103 + 8733737 = 8733840
109 + 8733731 = 8733840
127 + 8733713 = 8733840

Showing the first eight; more decompositions exist.
