Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30926, here are decompositions:

67 + 30859 = 30926
73 + 30853 = 30926
97 + 30829 = 30926
109 + 30817 = 30926
163 + 30763 = 30926
199 + 30727 = 30926
223 + 30703 = 30926
229 + 30697 = 30926

Showing the first eight; more decompositions exist.
