Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655618, here are decompositions:

7 + 8655611 = 8655618
197 + 8655421 = 8655618
269 + 8655349 = 8655618
311 + 8655307 = 8655618
331 + 8655287 = 8655618
359 + 8655259 = 8655618
401 + 8655217 = 8655618
421 + 8655197 = 8655618

Showing the first eight; more decompositions exist.
