Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663238, here are decompositions:

29 + 8663209 = 8663238
137 + 8663101 = 8663238
139 + 8663099 = 8663238
149 + 8663089 = 8663238
167 + 8663071 = 8663238
251 + 8662987 = 8663238
347 + 8662891 = 8663238
349 + 8662889 = 8663238

Showing the first eight; more decompositions exist.
