Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4056, here are decompositions:
- 5 + 4051 = 4056
- 7 + 4049 = 4056
- 29 + 4027 = 4056
- 37 + 4019 = 4056
- 43 + 4013 = 4056
- 53 + 4003 = 4056
- 67 + 3989 = 4056
- 89 + 3967 = 4056
Showing the first eight; more decompositions exist.
