Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618, here are decompositions:

19 + 8599 = 8618
37 + 8581 = 8618
79 + 8539 = 8618
97 + 8521 = 8618
151 + 8467 = 8618
157 + 8461 = 8618
199 + 8419 = 8618
229 + 8389 = 8618

Showing the first eight; more decompositions exist.
