Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 976, here are decompositions:

5 + 971 = 976
23 + 953 = 976
29 + 947 = 976
47 + 929 = 976
89 + 887 = 976
113 + 863 = 976
137 + 839 = 976
149 + 827 = 976

Showing the first eight; more decompositions exist.
