Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32780, here are decompositions:

31 + 32749 = 32780
61 + 32719 = 32780
67 + 32713 = 32780
73 + 32707 = 32780
127 + 32653 = 32780
193 + 32587 = 32780
211 + 32569 = 32780
277 + 32503 = 32780

Showing the first eight; more decompositions exist.
