Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628808, here are decompositions:

17 + 8628791 = 8628808
29 + 8628779 = 8628808
131 + 8628677 = 8628808
179 + 8628629 = 8628808
257 + 8628551 = 8628808
359 + 8628449 = 8628808
401 + 8628407 = 8628808
431 + 8628377 = 8628808

Showing the first eight; more decompositions exist.
