Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10978, here are decompositions:

5 + 10973 = 10978
29 + 10949 = 10978
41 + 10937 = 10978
89 + 10889 = 10978
131 + 10847 = 10978
179 + 10799 = 10978
197 + 10781 = 10978
239 + 10739 = 10978

Showing the first eight; more decompositions exist.
