Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30770, here are decompositions:

7 + 30763 = 30770
13 + 30757 = 30770
43 + 30727 = 30770
67 + 30703 = 30770
73 + 30697 = 30770
109 + 30661 = 30770
127 + 30643 = 30770
139 + 30631 = 30770

Showing the first eight; more decompositions exist.
