Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17618, here are decompositions:

19 + 17599 = 17618
37 + 17581 = 17618
67 + 17551 = 17618
79 + 17539 = 17618
109 + 17509 = 17618
127 + 17491 = 17618
151 + 17467 = 17618
199 + 17419 = 17618

Showing the first eight; more decompositions exist.
