Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627128, here are decompositions:

17 + 8627111 = 8627128
47 + 8627081 = 8627128
71 + 8627057 = 8627128
227 + 8626901 = 8627128
281 + 8626847 = 8627128
317 + 8626811 = 8627128
431 + 8626697 = 8627128
599 + 8626529 = 8627128

Showing the first eight; more decompositions exist.
