Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101730, here are decompositions:

7 + 101723 = 101730
11 + 101719 = 101730
29 + 101701 = 101730
37 + 101693 = 101730
67 + 101663 = 101730
89 + 101641 = 101730
103 + 101627 = 101730
127 + 101603 = 101730

Showing the first eight; more decompositions exist.
