Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741680, here are decompositions:

41 + 8741639 = 8741680
71 + 8741609 = 8741680
317 + 8741363 = 8741680
359 + 8741321 = 8741680
401 + 8741279 = 8741680
449 + 8741231 = 8741680
557 + 8741123 = 8741680
809 + 8740871 = 8741680

Showing the first eight; more decompositions exist.
