Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18698, here are decompositions:

7 + 18691 = 18698
19 + 18679 = 18698
37 + 18661 = 18698
61 + 18637 = 18698
157 + 18541 = 18698
181 + 18517 = 18698
241 + 18457 = 18698
271 + 18427 = 18698

Showing the first eight; more decompositions exist.
