Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723494, here are decompositions:

11 + 8723483 = 8723494
53 + 8723441 = 8723494
71 + 8723423 = 8723494
107 + 8723387 = 8723494
173 + 8723321 = 8723494
191 + 8723303 = 8723494
251 + 8723243 = 8723494
281 + 8723213 = 8723494

Showing the first eight; more decompositions exist.
