Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724518, here are decompositions:

7 + 8724511 = 8724518
31 + 8724487 = 8724518
97 + 8724421 = 8724518
199 + 8724319 = 8724518
277 + 8724241 = 8724518
337 + 8724181 = 8724518
349 + 8724169 = 8724518
379 + 8724139 = 8724518

Showing the first eight; more decompositions exist.
