Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739840, here are decompositions:

13 + 8739827 = 8739840
17 + 8739823 = 8739840
19 + 8739821 = 8739840
29 + 8739811 = 8739840
37 + 8739803 = 8739840
71 + 8739769 = 8739840
73 + 8739767 = 8739840
101 + 8739739 = 8739840

Showing the first eight; more decompositions exist.
