Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 35840, here are decompositions:

3 + 35837 = 35840
31 + 35809 = 35840
37 + 35803 = 35840
43 + 35797 = 35840
109 + 35731 = 35840
163 + 35677 = 35840
223 + 35617 = 35840
271 + 35569 = 35840

Showing the first eight; more decompositions exist.
