Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741320, here are decompositions:

11 + 8741309 = 8741320
17 + 8741303 = 8741320
41 + 8741279 = 8741320
89 + 8741231 = 8741320
167 + 8741153 = 8741320
173 + 8741147 = 8741320
179 + 8741141 = 8741320
191 + 8741129 = 8741320

Showing the first eight; more decompositions exist.
