Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739440, here are decompositions:

7 + 8739433 = 8739440
43 + 8739397 = 8739440
103 + 8739337 = 8739440
109 + 8739331 = 8739440
271 + 8739169 = 8739440
277 + 8739163 = 8739440
313 + 8739127 = 8739440
433 + 8739007 = 8739440

Showing the first eight; more decompositions exist.
