Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741488, here are decompositions:

17 + 8741471 = 8741488
29 + 8741459 = 8741488
167 + 8741321 = 8741488
179 + 8741309 = 8741488
257 + 8741231 = 8741488
347 + 8741141 = 8741488
359 + 8741129 = 8741488
389 + 8741099 = 8741488

Showing the first eight; more decompositions exist.
