Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662618, here are decompositions:

101 + 8662517 = 8662618
131 + 8662487 = 8662618
137 + 8662481 = 8662618
269 + 8662349 = 8662618
281 + 8662337 = 8662618
359 + 8662259 = 8662618
401 + 8662217 = 8662618
431 + 8662187 = 8662618

Showing the first eight; more decompositions exist.
