Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631208, here are decompositions:

17 + 8631191 = 8631208
41 + 8631167 = 8631208
167 + 8631041 = 8631208
191 + 8631017 = 8631208
197 + 8631011 = 8631208
347 + 8630861 = 8631208
419 + 8630789 = 8631208
449 + 8630759 = 8631208

Showing the first eight; more decompositions exist.
