Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101982, here are decompositions:

5 + 101977 = 101982
19 + 101963 = 101982
43 + 101939 = 101982
53 + 101929 = 101982
61 + 101921 = 101982
103 + 101879 = 101982
109 + 101873 = 101982
113 + 101869 = 101982

Showing the first eight; more decompositions exist.
