Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101724, here are decompositions:

5 + 101719 = 101724
23 + 101701 = 101724
31 + 101693 = 101724
43 + 101681 = 101724
61 + 101663 = 101724
71 + 101653 = 101724
83 + 101641 = 101724
97 + 101627 = 101724

Showing the first eight; more decompositions exist.
