Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32840, here are decompositions:

7 + 32833 = 32840
37 + 32803 = 32840
43 + 32797 = 32840
61 + 32779 = 32840
127 + 32713 = 32840
193 + 32647 = 32840
229 + 32611 = 32840
271 + 32569 = 32840

Showing the first eight; more decompositions exist.
