Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40144, here are decompositions:
- 17 + 40127 = 40144
- 107 + 40037 = 40144
- 113 + 40031 = 40144
- 131 + 40013 = 40144
- 173 + 39971 = 40144
- 191 + 39953 = 40144
- 257 + 39887 = 40144
- 281 + 39863 = 40144
Showing the first eight; more decompositions exist.
