Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18998, here are decompositions:

19 + 18979 = 18998
79 + 18919 = 18998
139 + 18859 = 18998
211 + 18787 = 18998
241 + 18757 = 18998
307 + 18691 = 18998
337 + 18661 = 18998
457 + 18541 = 18998

Showing the first eight; more decompositions exist.
