Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748388, here are decompositions:

29 + 8748359 = 8748388
59 + 8748329 = 8748388
101 + 8748287 = 8748388
107 + 8748281 = 8748388
179 + 8748209 = 8748388
197 + 8748191 = 8748388
227 + 8748161 = 8748388
251 + 8748137 = 8748388

Showing the first eight; more decompositions exist.
