Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722398, here are decompositions:

5 + 8722393 = 8722398
7 + 8722391 = 8722398
31 + 8722367 = 8722398
37 + 8722361 = 8722398
59 + 8722339 = 8722398
67 + 8722331 = 8722398
101 + 8722297 = 8722398
107 + 8722291 = 8722398

Showing the first eight; more decompositions exist.
