Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18488, here are decompositions:

7 + 18481 = 18488
31 + 18457 = 18488
37 + 18451 = 18488
61 + 18427 = 18488
109 + 18379 = 18488
181 + 18307 = 18488
199 + 18289 = 18488
271 + 18217 = 18488

Showing the first eight; more decompositions exist.
