Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662888, here are decompositions:

29 + 8662859 = 8662888
89 + 8662799 = 8662888
137 + 8662751 = 8662888
239 + 8662649 = 8662888
347 + 8662541 = 8662888
401 + 8662487 = 8662888
491 + 8662397 = 8662888
569 + 8662319 = 8662888

Showing the first eight; more decompositions exist.
