Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4038, here are decompositions:
- 11 + 4027 = 4038
- 17 + 4021 = 4038
- 19 + 4019 = 4038
- 31 + 4007 = 4038
- 37 + 4001 = 4038
- 71 + 3967 = 4038
- 107 + 3931 = 4038
- 109 + 3929 = 4038
Showing the first eight; more decompositions exist.
