Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631230, here are decompositions:

31 + 8631199 = 8631230
37 + 8631193 = 8631230
79 + 8631151 = 8631230
193 + 8631037 = 8631230
229 + 8631001 = 8631230
331 + 8630899 = 8631230
373 + 8630857 = 8631230
379 + 8630851 = 8631230

Showing the first eight; more decompositions exist.
