Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39988, here are decompositions:

5 + 39983 = 39988
17 + 39971 = 39988
59 + 39929 = 39988
101 + 39887 = 39988
131 + 39857 = 39988
149 + 39839 = 39988
167 + 39821 = 39988
197 + 39791 = 39988

Showing the first eight; more decompositions exist.
