Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740900, here are decompositions:

29 + 8740871 = 8740900
41 + 8740859 = 8740900
59 + 8740841 = 8740900
101 + 8740799 = 8740900
107 + 8740793 = 8740900
137 + 8740763 = 8740900
173 + 8740727 = 8740900
251 + 8740649 = 8740900

Showing the first eight; more decompositions exist.
