Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724300, here are decompositions:

7 + 8724293 = 8724300
17 + 8724283 = 8724300
31 + 8724269 = 8724300
37 + 8724263 = 8724300
41 + 8724259 = 8724300
47 + 8724253 = 8724300
59 + 8724241 = 8724300
131 + 8724169 = 8724300

Showing the first eight; more decompositions exist.
