Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747982, here are decompositions:

11 + 8747971 = 8747982
41 + 8747941 = 8747982
53 + 8747929 = 8747982
79 + 8747903 = 8747982
151 + 8747831 = 8747982
163 + 8747819 = 8747982
179 + 8747803 = 8747982
193 + 8747789 = 8747982

Showing the first eight; more decompositions exist.
