Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101940, here are decompositions:

11 + 101929 = 101940
19 + 101921 = 101940
23 + 101917 = 101940
61 + 101879 = 101940
67 + 101873 = 101940
71 + 101869 = 101940
101 + 101839 = 101940
103 + 101837 = 101940

Showing the first eight; more decompositions exist.
