Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626040, here are decompositions:

43 + 8625997 = 8626040
61 + 8625979 = 8626040
67 + 8625973 = 8626040
79 + 8625961 = 8626040
127 + 8625913 = 8626040
139 + 8625901 = 8626040
151 + 8625889 = 8626040
229 + 8625811 = 8626040

Showing the first eight; more decompositions exist.
