Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741218, here are decompositions:

71 + 8741147 = 8741218
89 + 8741129 = 8741218
347 + 8740871 = 8741218
359 + 8740859 = 8741218
419 + 8740799 = 8741218
461 + 8740757 = 8741218
491 + 8740727 = 8741218
569 + 8740649 = 8741218

Showing the first eight; more decompositions exist.
