Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626178, here are decompositions:

19 + 8626159 = 8626178
37 + 8626141 = 8626178
79 + 8626099 = 8626178
181 + 8625997 = 8626178
199 + 8625979 = 8626178
277 + 8625901 = 8626178
367 + 8625811 = 8626178
541 + 8625637 = 8626178

Showing the first eight; more decompositions exist.
