Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631632, here are decompositions:

3 + 8631629 = 8631632
181 + 8631451 = 8631632
241 + 8631391 = 8631632
313 + 8631319 = 8631632
349 + 8631283 = 8631632
433 + 8631199 = 8631632
439 + 8631193 = 8631632
523 + 8631109 = 8631632

Showing the first eight; more decompositions exist.
