Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4072, here are decompositions:
- 23 + 4049 = 4072
- 53 + 4019 = 4072
- 59 + 4013 = 4072
- 71 + 4001 = 4072
- 83 + 3989 = 4072
- 149 + 3923 = 4072
- 191 + 3881 = 4072
- 239 + 3833 = 4072
Showing the first eight; more decompositions exist.
