Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631444, here are decompositions:

43 + 8631401 = 8631444
53 + 8631391 = 8631444
71 + 8631373 = 8631444
103 + 8631341 = 8631444
113 + 8631331 = 8631444
137 + 8631307 = 8631444
167 + 8631277 = 8631444
193 + 8631251 = 8631444

Showing the first eight; more decompositions exist.
