Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39964, here are decompositions:

11 + 39953 = 39964
101 + 39863 = 39964
107 + 39857 = 39964
137 + 39827 = 39964
173 + 39791 = 39964
293 + 39671 = 39964
383 + 39581 = 39964
401 + 39563 = 39964

Showing the first eight; more decompositions exist.
