Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748242, here are decompositions:

43 + 8748199 = 8748242
199 + 8748043 = 8748242
211 + 8748031 = 8748242
241 + 8748001 = 8748242
271 + 8747971 = 8748242
313 + 8747929 = 8748242
379 + 8747863 = 8748242
439 + 8747803 = 8748242

Showing the first eight; more decompositions exist.
