Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724312, here are decompositions:

11 + 8724301 = 8724312
19 + 8724293 = 8724312
29 + 8724283 = 8724312
43 + 8724269 = 8724312
53 + 8724259 = 8724312
59 + 8724253 = 8724312
71 + 8724241 = 8724312
89 + 8724223 = 8724312

Showing the first eight; more decompositions exist.
