Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30740, here are decompositions:

13 + 30727 = 30740
37 + 30703 = 30740
43 + 30697 = 30740
79 + 30661 = 30740
97 + 30643 = 30740
103 + 30637 = 30740
109 + 30631 = 30740
163 + 30577 = 30740

Showing the first eight; more decompositions exist.
