Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741640, here are decompositions:

31 + 8741609 = 8741640
107 + 8741533 = 8741640
137 + 8741503 = 8741640
181 + 8741459 = 8741640
239 + 8741401 = 8741640
269 + 8741371 = 8741640
277 + 8741363 = 8741640
293 + 8741347 = 8741640

Showing the first eight; more decompositions exist.
