Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748842, here are decompositions:

31 + 8748811 = 8748842
103 + 8748739 = 8748842
199 + 8748643 = 8748842
241 + 8748601 = 8748842
373 + 8748469 = 8748842
379 + 8748463 = 8748842
439 + 8748403 = 8748842
643 + 8748199 = 8748842

Showing the first eight; more decompositions exist.
