Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673638, here are decompositions:

37 + 8673601 = 8673638
67 + 8673571 = 8673638
139 + 8673499 = 8673638
277 + 8673361 = 8673638
367 + 8673271 = 8673638
439 + 8673199 = 8673638
541 + 8673097 = 8673638
601 + 8673037 = 8673638

Showing the first eight; more decompositions exist.
