Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743638, here are decompositions:

5 + 8743633 = 8743638
17 + 8743621 = 8743638
41 + 8743597 = 8743638
67 + 8743571 = 8743638
89 + 8743549 = 8743638
107 + 8743531 = 8743638
139 + 8743499 = 8743638
149 + 8743489 = 8743638

Showing the first eight; more decompositions exist.
