Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101742, here are decompositions:

5 + 101737 = 101742
19 + 101723 = 101742
23 + 101719 = 101742
41 + 101701 = 101742
61 + 101681 = 101742
79 + 101663 = 101742
89 + 101653 = 101742
101 + 101641 = 101742

Showing the first eight; more decompositions exist.
