Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30936, here are decompositions:

5 + 30931 = 30936
43 + 30893 = 30936
67 + 30869 = 30936
83 + 30853 = 30936
97 + 30839 = 30936
107 + 30829 = 30936
127 + 30809 = 30936
163 + 30773 = 30936

Showing the first eight; more decompositions exist.
