Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748640, here are decompositions:

41 + 8748599 = 8748640
53 + 8748587 = 8748640
59 + 8748581 = 8748640
137 + 8748503 = 8748640
167 + 8748473 = 8748640
227 + 8748413 = 8748640
281 + 8748359 = 8748640
311 + 8748329 = 8748640

Showing the first eight; more decompositions exist.
