Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741578, here are decompositions:

107 + 8741471 = 8741578
257 + 8741321 = 8741578
269 + 8741309 = 8741578
347 + 8741231 = 8741578
431 + 8741147 = 8741578
449 + 8741129 = 8741578
479 + 8741099 = 8741578
719 + 8740859 = 8741578

Showing the first eight; more decompositions exist.
