Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631784, here are decompositions:

3 + 8631781 = 8631784
41 + 8631743 = 8631784
47 + 8631737 = 8631784
71 + 8631713 = 8631784
167 + 8631617 = 8631784
173 + 8631611 = 8631784
251 + 8631533 = 8631784
383 + 8631401 = 8631784

Showing the first eight; more decompositions exist.
