Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71998, here are decompositions:

5 + 71993 = 71998
11 + 71987 = 71998
89 + 71909 = 71998
131 + 71867 = 71998
137 + 71861 = 71998
149 + 71849 = 71998
191 + 71807 = 71998
257 + 71741 = 71998

Showing the first eight; more decompositions exist.
