Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3788, here are decompositions:
- 19 + 3769 = 3788
- 61 + 3727 = 3788
- 79 + 3709 = 3788
- 97 + 3691 = 3788
- 151 + 3637 = 3788
- 157 + 3631 = 3788
- 181 + 3607 = 3788
- 229 + 3559 = 3788
Showing the first eight; more decompositions exist.
