Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747968, here are decompositions:

11 + 8747957 = 8747968
41 + 8747927 = 8747968
137 + 8747831 = 8747968
149 + 8747819 = 8747968
179 + 8747789 = 8747968
191 + 8747777 = 8747968
389 + 8747579 = 8747968
479 + 8747489 = 8747968

Showing the first eight; more decompositions exist.
