Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41840, here are decompositions:

31 + 41809 = 41840
79 + 41761 = 41840
103 + 41737 = 41840
181 + 41659 = 41840
193 + 41647 = 41840
199 + 41641 = 41840
223 + 41617 = 41840
229 + 41611 = 41840

Showing the first eight; more decompositions exist.
