Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43040, here are decompositions:
- 3 + 43037 = 43040
- 37 + 43003 = 43040
- 61 + 42979 = 43040
- 73 + 42967 = 43040
- 79 + 42961 = 43040
- 97 + 42943 = 43040
- 103 + 42937 = 43040
- 139 + 42901 = 43040
Showing the first eight; more decompositions exist.
