Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724310, here are decompositions:

17 + 8724293 = 8724310
41 + 8724269 = 8724310
47 + 8724263 = 8724310
149 + 8724161 = 8724310
167 + 8724143 = 8724310
239 + 8724071 = 8724310
317 + 8723993 = 8724310
359 + 8723951 = 8724310

Showing the first eight; more decompositions exist.
