Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11998, here are decompositions:

11 + 11987 = 11998
17 + 11981 = 11998
29 + 11969 = 11998
59 + 11939 = 11998
71 + 11927 = 11998
89 + 11909 = 11998
101 + 11897 = 11998
131 + 11867 = 11998

Showing the first eight; more decompositions exist.
