Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4012, here are decompositions:
- 5 + 4007 = 4012
- 11 + 4001 = 4012
- 23 + 3989 = 4012
- 83 + 3929 = 4012
- 89 + 3923 = 4012
- 101 + 3911 = 4012
- 131 + 3881 = 4012
- 149 + 3863 = 4012
Showing the first eight; more decompositions exist.
