Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740920, here are decompositions:

29 + 8740891 = 8740920
53 + 8740867 = 8740920
61 + 8740859 = 8740920
79 + 8740841 = 8740920
113 + 8740807 = 8740920
127 + 8740793 = 8740920
131 + 8740789 = 8740920
137 + 8740783 = 8740920

Showing the first eight; more decompositions exist.
