Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741380, here are decompositions:

17 + 8741363 = 8741380
59 + 8741321 = 8741380
71 + 8741309 = 8741380
101 + 8741279 = 8741380
149 + 8741231 = 8741380
227 + 8741153 = 8741380
233 + 8741147 = 8741380
239 + 8741141 = 8741380

Showing the first eight; more decompositions exist.
