Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739408, here are decompositions:

11 + 8739397 = 8739408
17 + 8739391 = 8739408
19 + 8739389 = 8739408
59 + 8739349 = 8739408
71 + 8739337 = 8739408
109 + 8739299 = 8739408
127 + 8739281 = 8739408
199 + 8739209 = 8739408

Showing the first eight; more decompositions exist.
