Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726988, here are decompositions:

5 + 8726983 = 8726988
19 + 8726969 = 8726988
31 + 8726957 = 8726988
71 + 8726917 = 8726988
139 + 8726849 = 8726988
199 + 8726789 = 8726988
211 + 8726777 = 8726988
227 + 8726761 = 8726988

Showing the first eight; more decompositions exist.
