Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101998, here are decompositions:

11 + 101987 = 101998
41 + 101957 = 101998
59 + 101939 = 101998
107 + 101891 = 101998
191 + 101807 = 101998
227 + 101771 = 101998
251 + 101747 = 101998
257 + 101741 = 101998

Showing the first eight; more decompositions exist.
