Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724224, here are decompositions:

43 + 8724181 = 8724224
97 + 8724127 = 8724224
151 + 8724073 = 8724224
211 + 8724013 = 8724224
277 + 8723947 = 8724224
331 + 8723893 = 8724224
337 + 8723887 = 8724224
373 + 8723851 = 8724224

Showing the first eight; more decompositions exist.
