Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740978, here are decompositions:

107 + 8740871 = 8740978
137 + 8740841 = 8740978
179 + 8740799 = 8740978
251 + 8740727 = 8740978
401 + 8740577 = 8740978
419 + 8740559 = 8740978
461 + 8740517 = 8740978
641 + 8740337 = 8740978

Showing the first eight; more decompositions exist.
