Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724306, here are decompositions:

5 + 8724301 = 8724306
13 + 8724293 = 8724306
23 + 8724283 = 8724306
37 + 8724269 = 8724306
43 + 8724263 = 8724306
47 + 8724259 = 8724306
53 + 8724253 = 8724306
83 + 8724223 = 8724306

Showing the first eight; more decompositions exist.
