Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628078, here are decompositions:

29 + 8628049 = 8628078
47 + 8628031 = 8628078
59 + 8628019 = 8628078
61 + 8628017 = 8628078
71 + 8628007 = 8628078
101 + 8627977 = 8628078
131 + 8627947 = 8628078
139 + 8627939 = 8628078

Showing the first eight; more decompositions exist.
