Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31776, here are decompositions:

5 + 31771 = 31776
7 + 31769 = 31776
47 + 31729 = 31776
53 + 31723 = 31776
89 + 31687 = 31776
109 + 31667 = 31776
113 + 31663 = 31776
127 + 31649 = 31776

Showing the first eight; more decompositions exist.
