Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627944, here are decompositions:

5 + 8627939 = 8627944
41 + 8627903 = 8627944
47 + 8627897 = 8627944
131 + 8627813 = 8627944
137 + 8627807 = 8627944
167 + 8627777 = 8627944
251 + 8627693 = 8627944
263 + 8627681 = 8627944

Showing the first eight; more decompositions exist.
