Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747980, here are decompositions:

23 + 8747957 = 8747980
47 + 8747933 = 8747980
53 + 8747927 = 8747980
89 + 8747891 = 8747980
149 + 8747831 = 8747980
173 + 8747807 = 8747980
191 + 8747789 = 8747980
233 + 8747747 = 8747980

Showing the first eight; more decompositions exist.
