Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626128, here are decompositions:

19 + 8626109 = 8626128
29 + 8626099 = 8626128
61 + 8626067 = 8626128
67 + 8626061 = 8626128
127 + 8626001 = 8626128
131 + 8625997 = 8626128
149 + 8625979 = 8626128
167 + 8625961 = 8626128

Showing the first eight; more decompositions exist.
