Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626378, here are decompositions:

29 + 8626349 = 8626378
107 + 8626271 = 8626378
149 + 8626229 = 8626378
197 + 8626181 = 8626378
239 + 8626139 = 8626378
269 + 8626109 = 8626378
311 + 8626067 = 8626378
317 + 8626061 = 8626378

Showing the first eight; more decompositions exist.
