Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722370, here are decompositions:

3 + 8722367 = 8722370
31 + 8722339 = 8722370
37 + 8722333 = 8722370
67 + 8722303 = 8722370
73 + 8722297 = 8722370
79 + 8722291 = 8722370
199 + 8722171 = 8722370
271 + 8722099 = 8722370

Showing the first eight; more decompositions exist.
