Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631190, here are decompositions:

23 + 8631167 = 8631190
107 + 8631083 = 8631190
149 + 8631041 = 8631190
167 + 8631023 = 8631190
173 + 8631017 = 8631190
179 + 8631011 = 8631190
353 + 8630837 = 8631190
401 + 8630789 = 8631190

Showing the first eight; more decompositions exist.
