Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129830, here are decompositions:

37 + 129793 = 129830
61 + 129769 = 129830
67 + 129763 = 129830
73 + 129757 = 129830
97 + 129733 = 129830
199 + 129631 = 129830
223 + 129607 = 129830
241 + 129589 = 129830

Showing the first eight; more decompositions exist.
