Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719378, here are decompositions:

11 + 8719367 = 8719378
29 + 8719349 = 8719378
71 + 8719307 = 8719378
89 + 8719289 = 8719378
167 + 8719211 = 8719378
179 + 8719199 = 8719378
191 + 8719187 = 8719378
251 + 8719127 = 8719378

Showing the first eight; more decompositions exist.
