Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4042, here are decompositions:
- 23 + 4019 = 4042
- 29 + 4013 = 4042
- 41 + 4001 = 4042
- 53 + 3989 = 4042
- 113 + 3929 = 4042
- 131 + 3911 = 4042
- 179 + 3863 = 4042
- 191 + 3851 = 4042
Showing the first eight; more decompositions exist.
