Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724328, here are decompositions:

5 + 8724323 = 8724328
17 + 8724311 = 8724328
59 + 8724269 = 8724328
167 + 8724161 = 8724328
227 + 8724101 = 8724328
257 + 8724071 = 8724328
419 + 8723909 = 8724328
449 + 8723879 = 8724328

Showing the first eight; more decompositions exist.
