Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747940, here are decompositions:

7 + 8747933 = 8747940
11 + 8747929 = 8747940
13 + 8747927 = 8747940
23 + 8747917 = 8747940
37 + 8747903 = 8747940
83 + 8747857 = 8747940
109 + 8747831 = 8747940
137 + 8747803 = 8747940

Showing the first eight; more decompositions exist.
