Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748320, here are decompositions:

43 + 8748277 = 8748320
211 + 8748109 = 8748320
223 + 8748097 = 8748320
277 + 8748043 = 8748320
349 + 8747971 = 8748320
379 + 8747941 = 8748320
457 + 8747863 = 8748320
463 + 8747857 = 8748320

Showing the first eight; more decompositions exist.
