Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3738, here are decompositions:
- 5 + 3733 = 3738
- 11 + 3727 = 3738
- 19 + 3719 = 3738
- 29 + 3709 = 3738
- 37 + 3701 = 3738
- 41 + 3697 = 3738
- 47 + 3691 = 3738
- 61 + 3677 = 3738
Showing the first eight; more decompositions exist.
