Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631542, here are decompositions:

43 + 8631499 = 8631542
151 + 8631391 = 8631542
163 + 8631379 = 8631542
211 + 8631331 = 8631542
223 + 8631319 = 8631542
313 + 8631229 = 8631542
349 + 8631193 = 8631542
433 + 8631109 = 8631542

Showing the first eight; more decompositions exist.
