Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631358, here are decompositions:

17 + 8631341 = 8631358
89 + 8631269 = 8631358
107 + 8631251 = 8631358
167 + 8631191 = 8631358
191 + 8631167 = 8631358
317 + 8631041 = 8631358
347 + 8631011 = 8631358
521 + 8630837 = 8631358

Showing the first eight; more decompositions exist.
