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.
