Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40944, here are decompositions:
- 5 + 40939 = 40944
- 11 + 40933 = 40944
- 17 + 40927 = 40944
- 41 + 40903 = 40944
- 47 + 40897 = 40944
- 61 + 40883 = 40944
- 97 + 40847 = 40944
- 103 + 40841 = 40944
Showing the first eight; more decompositions exist.
