Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617618, here are decompositions:

71 + 8617547 = 8617618
179 + 8617439 = 8617618
227 + 8617391 = 8617618
257 + 8617361 = 8617618
431 + 8617187 = 8617618
509 + 8617109 = 8617618
521 + 8617097 = 8617618
617 + 8617001 = 8617618

Showing the first eight; more decompositions exist.
