Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673640, here are decompositions:

29 + 8673611 = 8673640
47 + 8673593 = 8673640
71 + 8673569 = 8673640
251 + 8673389 = 8673640
263 + 8673377 = 8673640
281 + 8673359 = 8673640
293 + 8673347 = 8673640
347 + 8673293 = 8673640

Showing the first eight; more decompositions exist.
