Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748238, here are decompositions:

29 + 8748209 = 8748238
47 + 8748191 = 8748238
71 + 8748167 = 8748238
101 + 8748137 = 8748238
227 + 8748011 = 8748238
251 + 8747987 = 8748238
281 + 8747957 = 8748238
311 + 8747927 = 8748238

Showing the first eight; more decompositions exist.
