Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40978, here are decompositions:

5 + 40973 = 40978
17 + 40961 = 40978
29 + 40949 = 40978
131 + 40847 = 40978
137 + 40841 = 40978
149 + 40829 = 40978
191 + 40787 = 40978
227 + 40751 = 40978

Showing the first eight; more decompositions exist.
