Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4126, here are decompositions:
- 47 + 4079 = 4126
- 53 + 4073 = 4126
- 107 + 4019 = 4126
- 113 + 4013 = 4126
- 137 + 3989 = 4126
- 179 + 3947 = 4126
- 197 + 3929 = 4126
- 263 + 3863 = 4126
Showing the first eight; more decompositions exist.
