Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728374, here are decompositions:

43 + 8728331 = 8728374
71 + 8728303 = 8728374
101 + 8728273 = 8728374
113 + 8728261 = 8728374
163 + 8728211 = 8728374
167 + 8728207 = 8728374
181 + 8728193 = 8728374
227 + 8728147 = 8728374

Showing the first eight; more decompositions exist.
