Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27964, here are decompositions:

3 + 27961 = 27964
11 + 27953 = 27964
17 + 27947 = 27964
23 + 27941 = 27964
47 + 27917 = 27964
71 + 27893 = 27964
113 + 27851 = 27964
137 + 27827 = 27964

Showing the first eight; more decompositions exist.
