Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40880, here are decompositions:

13 + 40867 = 40880
31 + 40849 = 40880
61 + 40819 = 40880
67 + 40813 = 40880
79 + 40801 = 40880
109 + 40771 = 40880
181 + 40699 = 40880
241 + 40639 = 40880

Showing the first eight; more decompositions exist.
