Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971984, here are decompositions:

3 + 971981 = 971984
7 + 971977 = 971984
67 + 971917 = 971984
127 + 971857 = 971984
151 + 971833 = 971984
163 + 971821 = 971984
271 + 971713 = 971984
331 + 971653 = 971984

Showing the first eight; more decompositions exist.
