Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724366, here are decompositions:

19 + 8724347 = 8724366
37 + 8724329 = 8724366
43 + 8724323 = 8724366
47 + 8724319 = 8724366
73 + 8724293 = 8724366
83 + 8724283 = 8724366
97 + 8724269 = 8724366
103 + 8724263 = 8724366

Showing the first eight; more decompositions exist.
