Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724254, here are decompositions:

13 + 8724241 = 8724254
31 + 8724223 = 8724254
73 + 8724181 = 8724254
127 + 8724127 = 8724254
181 + 8724073 = 8724254
241 + 8724013 = 8724254
277 + 8723977 = 8724254
307 + 8723947 = 8724254

Showing the first eight; more decompositions exist.
