Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662918, here are decompositions:

29 + 8662889 = 8662918
59 + 8662859 = 8662918
107 + 8662811 = 8662918
149 + 8662769 = 8662918
167 + 8662751 = 8662918
269 + 8662649 = 8662918
401 + 8662517 = 8662918
431 + 8662487 = 8662918

Showing the first eight; more decompositions exist.
