Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741278, here are decompositions:

47 + 8741231 = 8741278
131 + 8741147 = 8741278
137 + 8741141 = 8741278
149 + 8741129 = 8741278
179 + 8741099 = 8741278
419 + 8740859 = 8741278
479 + 8740799 = 8741278
521 + 8740757 = 8741278

Showing the first eight; more decompositions exist.
