Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741128, here are decompositions:

5 + 8741123 = 8741128
29 + 8741099 = 8741128
257 + 8740871 = 8741128
269 + 8740859 = 8741128
401 + 8740727 = 8741128
449 + 8740679 = 8741128
479 + 8740649 = 8741128
521 + 8740607 = 8741128

Showing the first eight; more decompositions exist.
