Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732840, here are decompositions:

7 + 8732833 = 8732840
43 + 8732797 = 8732840
97 + 8732743 = 8732840
163 + 8732677 = 8732840
199 + 8732641 = 8732840
241 + 8732599 = 8732840
367 + 8732473 = 8732840
379 + 8732461 = 8732840

Showing the first eight; more decompositions exist.
