Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740980, here are decompositions:

29 + 8740951 = 8740980
41 + 8740939 = 8740980
89 + 8740891 = 8740980
109 + 8740871 = 8740980
113 + 8740867 = 8740980
139 + 8740841 = 8740980
173 + 8740807 = 8740980
181 + 8740799 = 8740980

Showing the first eight; more decompositions exist.
